Question

Use rational exponets to write
x (1/8) * y(1/5) * z(1/2)
as single radical expression.

Answer 1

yikes. like adding fractions, need a common denominator of 40
so
\[\frac{1}{8}=\frac{5}{40}\]
\[\frac{1}{5}=\frac{8}{40}\]
\[\frac{1}{2}=\frac{20}{40}\] and your answer is
\[\sqrt[40]{x^5y^8z^{20}}\]
