Question

I need some help with this question:

Which of the following best define 2/(3^3)

- Square root of 9
- Cube root of 9
- Cube root of 3
- Square root of 3

I believe the answer is cube root of 3 just because that's what my gut is feeling...

Answer 1

\(\dfrac{2}{3^3}\)?

Answer 2

Yes :)

Answer 3

are you sure?

Answer 4

\(\dfrac{2}{3^3}=\dfrac{2}{27}\) which is not on the list

Answer 5

are you sure its not \(3^{\frac{2}{3}}\)?

Answer 6

\(3^{\frac{2}{3}}=\sqrt[3]{3^2}=\sqrt[3]{9}\)

Answer 7

oooooh - okay I got it now

Answer 8

Thank you :)
