Evaluate the expression below when x = 27 and y = 16. Homework Help ✎

6x2/3y1/4 · x1y1/2

Start by simplifying the expression.
Remember that when you multiply numbers with the same base,
you can add the exponents together.

Substitute the given values for x and y then simplify.
Fractional exponents represent a power and a root.
The root is determined by the denominator, and the power by the numerator.
For example, the exponent for 16 means the 4th root of 16 raised to the 3rd power.
