Answer 1

Answer:

Step-by-step explanation:

Answer:11021

Step-by-step explanation:103x107

(100+3)(100+7)

Similar to (x+a)(x+b)=x²+(a+b)x+ab

So, =>100²+(3+7)100+(3x7)

=>10000+100x3+7x100+21

=>10000+300+700+21

=>11021 :)

Answer 2

Answer:

14552

Step-by-step explanation:

identity=(X+A)(X+B)=x^2 + (a+b)x +ab

136*107

(100+36)(100+7)           x=100

                                       a=36

                                       b=7

100^2 + (36+7)100 +36*7

= 10000+4300+252

=14552
