Question

204×208 by using suitable algebraic property

Answer 1

=(200+4) (200+8)

[(x+a) (x+b) =x^2+(a+b)x+ab]

x=200,a=4,b=8.

=200^2+(4+8)200+4x8
=40000+(12)200+32
=40000+2400+32
=42432

hope it hlpzzzz u.......

Answer 2

(200+4)(200+8)
(x+a)(x+b)= x^2 +(a+b)x+ab
200×200+(8+4)200+8×4
40000+2400+32=42432
