Answer:
Explanation:
Since the denominator of each of those rational exponents is a 4, that means that the radical is a 4th root. The numerator of each exponent serves as the power on the given base. For example,
can be rewritten as
![\sqrt[5]{2^3}](https://img.qammunity.org/2020/formulas/mathematics/middle-school/11i9iao0ae2g9rnrj2u3d3mqdkakrlar3f.png)
The little number that sits outside the radical, resting in the bend, is called the index. Our index is 4 (same as saying the 4th root). Put everything under the 4th root and let the numerator be the powers on each base:
which is written simpler as:
![\sqrt[4]{6b^3c}](https://img.qammunity.org/2020/formulas/mathematics/middle-school/rughtl9vech2r37gohqxm89hcmlunmve5g.png)
