Question

using identitities evaluate
95*103

Answer 1

Answer:

10815 is the answer

Step-by-step explanation:

95 : 100-5

103:100+3

so use identity(x+a)(x+ B) = x^2+(a+B)x+ab

x = 100

100^2+(3+5)100+3*5

10000+800+15

10815

Answer 2

Question

Using identities evaluate  :95*103

Solution:

      95 × 103

=  (100-5)( 100 +3)

[ ∵ (x+a)(x+b) = x²+ (a+b)x + ab ]

=  (100)² + (-5 + 3)(100) + (-5)(3)

=  10000 -200 -15

= 10000 -215

=  9785
