What is the sixth root of (2/3)^2 as a power

What that looks like under a radical is this:  .  The 6 is called the index and will replace the denominator in our power, and the 2 is the power on the base 2/3 which will replace the numerator in our final exponent.  So what we have, rewritten, is this: .  Of course that exponent can be reduced so what the actual exponent is is 1/3.  Our final simplified expression is
