## Homework Statement

Please help me understand how (v/pi)(2pi/v)

^{2/3}equals 2(v/2pi)

^{1/3}

This is from my book.

## The Attempt at a Solution

[(v)(2

^{2/3})(pi

^{2/3})]/v

^{2/3}pi = 2

^{2/3}(v/pi)

^{1/3}

What am I doing wrong? Thanks.

EDIT: I made a mistake in copying over my attempt; fixed now.
