# How do you write (4n)^2 without exponents?

There are many ways to write ${\left(4 n\right)}^{2}$ without exponents.
${\left(4 n\right)}^{2} = \left(4 n\right) \left(4 n\right) = 4 \cdot 4 \cdot n \cdot n = 16 {n}^{2}$
Now, we just have to choose a way to restate $16 {n}^{2}$
This can be written as $\left(4 n\right) \left(4 n\right)$, $\left(16 n\right) \left(n\right)$, or anything like that.
As long as the end product is $16 {n}^{2}$, then you can rewrite it to be anything that does not have exponents.
