Cube -: Cube ko hindi me "Ghan"(घन) kahate hai.
Kisi number ka cube calculate karne ka matalab hai, uss diye gaye number ka 3 times multiply karna hota hai.
Defination-:
" Kisi diye huye number ka 3 times multiply karna, uss diye huye number ka cube kahalata hai. "
For example-:
Suppose hume 2 ka cube calculate karna hai.
Solution -: 2³ = 2×2×2 = 8
Means 2 ka cube = 8
Or 2³ = 8
I hope aap cube k baare me jaan gaye honge. Ab mai aapko cube root k baare me batata hu.

Step-1. 5832 ka last digit = 2
Step-2. Cube and cube root table se
8³ = 51 2 ⬅ last digit
Isliye 8 diye huye number 5832 k cube root ka last digit hai.
Means, ³√5832 = 8
Step-3. Ab 5832 ka last 3 digit remove kare.
5832 = 5
Phir se table me dekhe ki "kis no. ka cube , 5 k equal ho ya small ho."
1³ = 1<5
Isliye 1 diye huye no. 5832 ka cube root ka second last digit hai.
Means, ³√5832 = 18 Ans.
Ex.-4. ³√19683 =??
Step -1. 19683 ka last digit = 3
Step -2. Table me dekhane par-:
7³ = 34 3 ⬅ last digit
Step -3. 19683 ka last 3 digit remove kare.
19 683 = 19
Table me dekhe ,
2³ = 8<19 (but 3 nhi kyuki 3² = 27 > 19)
Isliye 2 second last digit number hai.
³√19683 = 27 Ans.

Ex.-5. ³√54872 =??
Step-1. 54872 ka last digit = 2
Step-2. table me dekhe-:
8³ = 51 2 ⬅ last digit
Isliye 8 no. 54872 k cube root ka last digit no. hai.
Means, ³√54872 = 8
Step-3. 54872 ka last ka three digit remove kare.
54 872 = 54
Table me dekhe -:
3³ = 27<54
Isliye 3 diye huye number ka second last digit number hai.
Means , ³√54872 = 38 Ans.
Ex.-6. ³√117649=??

9³ = 72 9 ⬅ last digit
Isliye , ³√117649 = 9
117649 ka last 3 digit remove karne k baad-:
117 649 = 117
Table me phir se dekhe -:
4³ = 64<117
Isliye ³√117649 = 49 Ans.
Ex.-7. ³√157464 =??
Last digit = 4
Table me dekhe-:
4³ = 6 4 ⬅ last digit
Isliye ³√157464 = 4
157464 ka 3 digit remove -:
157 464 = 157
Table se -:
5³ = 125<157
Isliye ³√157464 = 54 Ans.
Ex.-8. ³√250047 =??

³√250047 = 3
3 digit remove -:
250 047 = 250
Table se , 6³ = 216<250
Isliye , ³√250047 = 63 Ans.
Ex-9. ³√421875 =??
Last digit = 5
Table se , 5³ = 125 ⬅ last digit
³√421875 = 5
3 digit remove -:
421 875 = 421
Table se , 7³ = 343<421
³√421875 = 75 Ans.
Ex.10. ³√884436 =??
Last digit = 6
Table se , 6³ = 21 6 ⬅ last digit
³√884436 = 6
3 digit remove -:
884 436 = 884
Table se , 9³ = 729<884
³√884436 = 96 Ans.
Aap niche diye video ko dekhe aapko ye shortcut trick aur behatar se samjh aajayega.
To friends maine 10 example ki help se aapko aaj ka shortcut tricks bataya. Aapko ye shortcut trick kaisa laga ? comment kark jarur bataye !

Fast cube root shortcut trick of any 4 to 6 digit numbers
Cube root ko shortcut se solve karne se pahale mai aapko batadu ki cube and cube root kya hota hai?What is cube ?
(Cube kya hai ?)

What is cube root ?
(Cube root kya hai ?)
Cube root -: cube root ko hindi me "Ghanmul"(घनमूल) kahte hai.
Cube root , cube ka just opposite hota hai .
Matalab maan lete hai kisi number "x" ka cube "y" hai . To "y" ka cube root "x" hota hai.
Aor isse iss type se denote karte hai-:
x³ = y
and ³√y = x
For example-: Humne uppar k example me dekha ki 2 ka cube 8 hota hai. Ab just iska ulta cube root hota hai.
Means , 8 ka cube root 2 hota hai.
I hope aapko cube and Cube root clear ho gaya hoga .
Ab mai apne shortcut trick par aata hu.
Chaliye to aaj ka trick start karte hai , friends aapse ek request hai ki aap ek pen and paper le lo aur mai jaise-jaise batata hu vaise-vaise mere saath kartey jaaye taki aapko acche se samjh aaye.

Sabse pahle aap niche diye iss cube table ko Learn karle kyuki iss table ka hum cube root nikalne me use karenge.
Chaliye start karte hai, to kya aap pen and paper lekar ready hai? Agar aapka answer yes hai. To very good but agar aapne nhi liya to jaldi le lo oar mere saath practice karte jaaye.
To humara first example hai -:
Ex-1. ³√4913 =??
Step -1. sabse pahle diye huye number ka last digit choose kare.
4913 ka last digit = 3
Step-2. Ab cube table me dekhe ki, " Kis number k cube ka last digit 3 hai. "
To aap dekh sakte hai ki
7³ = 34 3 ⬅ last digit
Yahi number 7 diye huye number 4913 k cube root ka last digit number hai.
Means, ³√4913 = 7
Ab hume second last digit number ko find karna hai.
Step-3. Diye huye number 4913 ka last three digit tak k number ko remove (gaayab) kare.Jaise maine niche kiya hai.
4913 = 4
Three digit remove karne k baad humare pass 4 hai.
Step-4. Ab cube table me dekhe ki , kis number ka cube "4" k equal ya small hai. Aur usse choose kar le.
Aap dekh sakte hai ki ,
1³ = 1
1<4 hai, ( but 2³ = 8>1 hai Isliye 2 nhi choose kar sakte)
Yahi number "1" diye huye number 4913 k cube root ka second last digit number hai.
Matalab , ³√4913 = 17 Ans.

Ex.-2. ³√1331 =??
Step -1. 1331 ka last digit choose kare.
Last digit = 1
Step-2. Ab upar diye huye cube table me dekhe ki , kis number k "cube" ka "last digit "1" hai, to aap dekh sakte hai ki 1 k cube = 1 ka last digit "1" hai.
Means
1³ = 1⬅ last digit
Yahi number "1" diye huye number 1331 k cube root ka last digit ka number hai.
Means, ³√1331 = 1
Humne 1331 cube root ka last digit maalum kar liya . Ab hum second last digit matalab tens place ka number maalum karenge.
Step-3. Ab diye huye number 1331 se last k three digit number ko remove ( gaayab ) kar de.
1331 = 1
Ab diye huye cube table me dekhe ki , kis number ka cube "1" k equal ya small aa raha hai.
Aap dekh sakte hai ki
1³ = 1 = 1 k barabar hai isliye "1" hi humare 1331 k cube root ka second last digit number hoga.
Means, ³√1331 = 11 Ans.
Ex.-3. ³√5832=??Cube root , cube ka just opposite hota hai .
Matalab maan lete hai kisi number "x" ka cube "y" hai . To "y" ka cube root "x" hota hai.
