Question

How can you simplify this expression. Please Help!!

Answer 1

\[(\frac{ t ^{4} }{ 10 y ^{4}})^{-4}\]

Answer 2

The negative exponent says that whatever is on top should go underneath, and whatever is underneath should go on top.

So flip the fraction and change the negative exponent to a positive exponent

Answer 3

So now it's

\[(\frac{10y^4 }{ t^4 })^4\]

Answer 4

Then just distribute the exponent "4"
