What is the difference between $9^2\mathrm{and}\sqrt{9}$?

Population growth The expression $10.x^n$models the growth of a mold population after $n$generations. There were $10$ spores at the start, and
each had $x$offspring. So$10.x^n$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.
