Question

8th root of 8y to the 16th power

Answer 1

assuming you want to simplify

your question looks like this:
`\sqrt[8y]{ x^(16) }`

remember the exponential law that says

`x^{ (m)/(n) }= \sqrt[n]{ x^(m) }` so therefor

`\sqrt[8]{ 8y^(16) }` =
`8y^{ (16)/(8) }`
simplify the fraction
16/8=2/1=2

`8y^{ (16)/(8) }`=
`8y^(2)`
