What is the equivalent of 243 to the power of (2/5)
nasty-shy [4]

<span>(243)^(2/5) = ?
---
The 5 in the denominator means "take the 5th root".
The 2 in the numerator means "square".

---


</span><span>Taking the 5th root first you get:
(243)^(2/5) = 3^2
Now squaring gives you
3^2 = 9

So the answer is 9.

Hope this helps :)
