How would the 4th root of (x^2y^4z^5) be written in exponential notation?

Answer 1

If this is really x raised to the 2y power which is then raised to the 4z power which is then raised to the 5th power, then it would be x raised to the 2y power raised to the 4z power raised to the 5/4 power:

x^2y^4z^(5/4)

Or perhaps you meant to find the 4th root of (x²y⁴z⁵), which would be x^2/4y^4/4z^5/4 = x^1/2yz^5/4
