Question

Prove that (100-100)/(10-10)=20

Answer 1

Step-by-step explanation:

100-100 = 20(10-10)

100-100 = 200 - 200

200+100 = 200+100

300 = 300

RHS=LHS

Answer 2

Step-by-step explanation:

10²-10² / (10 - 10)

a²-b²= (a + b) (a - b)

(10 + 10)(10-10) / (10 - 10)

we can cut (10 - 10) from the numerator and denominator and we will be left with (10 + 10)

(10 + 10) = 20

hence proved , (100-100)/(10-10)=20

Hope this helps you
