Question

prove that (100-100)/(100-10)=2​

Answer 1

Answer:

Step-by-step explanation:

First: 100-100=0,100-10=90,and 0/90 is not 2 so it’s false.

Answer 2

To prove: (100-100) /(100-100) =2

Proof:

[(10)^2-(10)^2]/[10(10-10)]

[(10+10)(10-10)]/[10(10-10)]

[10+10]/10

20/10=2.

Hence proved.Practically it is not possible, but by using some tricks a^2-b^2=(a+b)(a-b)

and (10-10) cancel from both sides.

A genius can only solve this.

"Note: A little editing in question it was 100-100 in denominator not 100 -10."
