Chaliye aaj ka square trick start karte hai.
Trick ka rule -:
Vaise to iss trick ko batane k liye trick k rule ki jarurat nhi padati. Mai aapko direct bata sakta hu , but aapko ye trick achhe se samjh aaye issliye trick ka rule jaruri hai.
Chaliye trick ka rule batata hu.
Maan lijiye "N5" ek number hai. Jiska last digit "5" hai .Jaha"N"=1,2,3,4........etc.
"N5" ka square karna hai tab trick ka rules -:
(N5)² = (N+1)×N/25
[Note-: Upper diye rules me"/" ka matalab "divide " nhi hai. Iska use kewal 2 number ko alag-alag likhane k liye kiya gaya hai.]

• Trigonometry ka basic concept in hindi part-1
• Kya aapko koi help mathematics me chahiye?
Chaliye ek simple example se tricks k rules ko apply Karna shikhate hai.
Ex-1. 25 ka square =?
Trick -: Tricks ka rules -
(N5)² =(N+1)×N/25
Iss example me "N"= 2
(25)² = (2+1)×2/25
= (3)×2/25
=6/25
=625
25 ka square =625 Ans.

25 ka square =625 Ans.
Aayiye kuch aor example dekhate hai-:
Ex-2. 15² = ??
Tricks-:
N = 1 , using formula -:
15² = (1+1)×1/25
= 2×1/25
= 225 Ans.
N = 1 , using formula -:
15² = (1+1)×1/25
= 2×1/25
= 225 Ans.
Ex-3. 35² = ??
Trick -: N = 3
Formula use karne par -:
35² = (3+1)×3/25
= 4×3/25
= 12/25
= 1,225 Ans.
Ex-4. 55² = ??
N = 5
Using formula -:
55² = (5+1)×5/25
= 6×5/25
= 30/25
= 3,025 Ans.
Ex-5. 85² = ??
Trick -: N = 8
85² = (8+1)×8/25
= 72/25
= 7,225 Ans.
Ex-6. 105² = ??
Trick-: 105 k liye "N" = 10
Ab formula ka use karne par-:
105² = (10+1)×10/25
= 11×10/25
= 110/25
= 11,025 Ans.
Ex-7. 145² = ??
Ab hum direct karte hai.
145² = (14+1)×14/25
= 15×14/25
= 210/25
= 21,025 Ans.
Ex-8. 175² = ??
Just in second -:
175²= 17×18/25
= 306/25
= 30,625 Ans.
Ex-9. 205² = ??
Trick-:
205² = 21×20/25
= 420/25
= 42,025 Ans.
Aayiye ek last example dekhate hai-:
Ex-10. 355² = ??
Trick-: N = 35
Formula use karne par-:
355² = (35+1)×35/25
= 36×35/25
= 1260/25
= 1,26,025 Ans.
