Question

Another one I get stumped on. I need an answer, please? Thanks! Question attached.

Answer 1

\[\sqrt[6]{64a^9} = \sqrt[6]{64} \sqrt[6]{a^9}\]
64 = 2 to the 6th power, then:
\[\sqrt[6]{64a^9} = 2 \sqrt[6]{a^9} = 2a^{9/6} = 2a^{3/2}\]

Answer 2

It said the answer was incorrect, but thanks anyways.

Answer 3

It is correct. What do you mean by "it"?

Answer 4

My computer program. I posted another.

Answer 5

But I give you medal for helping me :) Thanks

Answer 6

Another form of writing it:
\[2\sqrt{a^3}\]

Answer 7

That might have been right... i have no way to check now though.
