# How do you write the expression (n-5)(n-5)(n-5) using exponents?

Jan 9, 2017

${\left(n - 5\right)}^{3}$

#### Explanation:

$\left(n - 5\right) \left(n - 5\right) \left(n - 5\right)$

Let $n = 7$

Then $\left(7 - 5\right) \left(7 - 5\right) \left(7 - 5\right)$

$= 2 \times 2 \times 2 = {2}^{3} = 8$

So $\left(n - 5\right) \left(n - 5\right) \left(n - 5\right) = {\left(n - 5\right)}^{3}$
