Rational Exponents and Radicals

To simplify the given expression, we will use the properties of rational exponents. For this exercise, we will begin by using the Power of a Power Property.

(y^{- \frac{7}{5}})^{- \frac{1}{2}}

(a^{m})^{n} = a^{m \cdot n}

y^{- \frac{7}{5} (- \frac{1}{2})}

- a (- b) = a \cdot b

y^{\frac{7}{5} (\frac{1}{2})}

MultFracMultiply fractions

y^{\frac{7}{1 0}}
