Answer:
should be the answer of the problem that you posted
if you try to solve using as as
then = =
* 9b =
Explanation:
a's can be removed from the radicle (one will be left in because you have a^5)
9b /a^5/2
9√(a^-5 b^2)
9 sqrt( a^ -5 b^2)
Rewriting sqrt as ^1/2
9 ( a^ -5 b^2)^1/2
9 ( a^ -5) ^1/2 ( b^2)^1/2
we know that an exponent to an exponent means multiply
9 a^ (-5*1/2) b^(2*1/2)
9 a^-5/2 b^1
9b a^ -5/2
We know that x^-y = 1/x^y
