Question

simplify (3/5y^4)^-2

Answer 1

When you have a negative exponent you have to flip the problem to make it positive

Answer 2

\[(\frac{3}{5y^4})^{-2}\]
\[(\frac{5y^4}{3})^2\]
Use the rule
\[(\frac{m}{n})^p=\frac{m^p}{n^p}\]
solve

Answer 3

6/10y^16?

Answer 4

Nope

Answer 5

10y^16/6?

Answer 6

Well if you've used the rule, you would get
\[(\frac{5y^4}{3})^2 \\ =\frac{5^2(y^4)}{3^2}^2\]
