Higher Roots · Exercise 79

Population growth The expression $10\cdot x^n$ models the growth of a mold population after $n$ generations. There were 10 spores at the start, and each had $x$ offspring. So $10\cdot x^5$ is the number of offspring at the fifth generation. At the fifth generation there were 10,240 offspring. Simplify the expression $\sqrt[5]{\frac{10,240}{10}}$ to determine the number of offspring of each spore.

Its source prints no answer for this problem, so there's nothing to check against.
