Answer 1

Step-by-step explanation:

using the same method u can solve the eqn

Answer 2

Answer:

its an easy way to di this

Step-by-step explanation:

ok now look

(104)=(100+4)

(95)=(100-5)

in both we have a common no i. e. 100

so now using

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

x=100

a=4

b=-5

now putting the values in identity, we get

(100)2+100(4-5)+(4*-5)

10000+100-20

=1080
