Find the value of x needed to make the equation true.

3 (first choice)

A power to a power gives a multiplication of powers, e.g.,

(7¹⁰)² = 7²⁰

So the left side is 7²⁰ / 7⁴ and we divide the top and bottom by 7 get we

(7¹⁰)² / 7⁴ =  7²⁰ / 7⁴ = 7¹⁹ / 7³

We compare that to the right side  7¹⁹ / 7ˣ  and it's clear x=3.

is there any attachment? what are the equations?

sinn is the total amount of students now and m were the students before, you subtract them both (n-m) and divide that by m. then, since to get a percentage from a fraction you have to multiply by 100, your answer should look like this: n-m/m*100
