Question

y^-2= x^-3

is there a special rule to get rid of the -3 so i can just have something =x?

Answer 1

you could use this rule
\[ \left( a^b\right)^c = a^{bc}\]

Answer 2

in other words find the "c" that makes -3*c = 1

then raise both sides to that power (to keep it an equation)

Answer 3

wow! that was so obvious haha thnx!
