10 × 8 = 80 squared feet
(wall space)
5 × 3 = 15 squared feet
(area of the window)
80- 15 = 65 squared feet
(the amount of area she will be painting on)
Hello!

Recall that:
is equal to
. Therefore:
![\sqrt[3]{x^{2} } = x^{\frac{2}{3} }](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7Bx%5E%7B2%7D%20%7D%20%3D%20x%5E%7B%5Cfrac%7B2%7D%7B3%7D%20%7D)
There is also an exponent of '6' outside. According to exponential properties, when an exponent is within an exponent, you multiply them together. Therefore:

im just gonna take the points for falling for that.
