Write as a single power of 3.

1/(9(square root of 3))

I just can't figure it out without having a negative exponent.

-
1/(9√3)
= 1/[3^2 * 3^(1/2)]
= 1/[3^(2 + 1/2)]
= 1/3^(5/2)

-
1/(9(square root of 3))

If you mean 1/[9*sqrt(3)]

1/[3^2 * 3^(1/2)]

1/[3^2.5]

3^(-2.5)

The question asked for a single power; "-2.5" *is* a single power, albeit negative and not an integer.

-
1/(3^2 multiply 3^(1/2))=1/3^(5/2)=3^(-5/2)

-
1/(9(square root of 3)) = 1 / (9)^1/3 = 1 / 2.080084 = 0.48075 >=========< ANSWER
