Question

Please help!
Simplify. Your answer should contain only positive exponents.

Answer 1

`(1)/(4k^3)`

Explanation:

It's already in a form that only ha positive exponents. Just to state it though you could rewrite it as
`k*(4k^(4))^(-1)` or
`k*4^(-1)*k^(-4)` The question asks for positive exponents though so yu don't need to do that.

You also need to know
`(x^a)/(x^b)=x^(a-b)` so in this case
`(k)/(k^4)=(k^1)/(k^4) =k^(1-4)=k^(-3)=(1)/(k^3)`

so
`(k)/(4k^4)=(1)/(4)*(k)/(k^4)=(1)/(4)*(1)/(k^3)=(1)/(4k^3)`
