4y3
4/y^3
y^3/4
This expression is already simplified

Answer 1

when you have a negative exponent, it means that, the base of that exponent is on the other side of the fraction with the same exponent but positive.

so \(\large x^{-2}\) means \(\huge \frac{1}{x^{2}}\)

and

\(\huge \frac{1}{x^{-2}}=x^2 \)

do you understand this?

Answer 2

not really

Answer 3

wait i think i get it, so im just going to reveres x^2 into x^-2

Answer 4

when you want to reverse x^2, it becomes 1/x^-2

Answer 5

it's not called "reverse" anyway but i hope u get it now :)

Answer 6

i do thank you

Answer 7
