10 • 10 • (-n) • (-n) • (-n)

Step-by-step explanation:
We're going to simplify the problem with exponents.
Exponents are a shortened way for explaining how many times a number will multiply itself.
Example:
[tex]3 \times 3 \times 3. [/tex]
[tex] \: the \: number \: is \: multiplying \: by \: itself \: \: 3 \: times. \: the \: exponent \: is \: represented \: as: \:[/tex]
[tex] {3}^{3} [/tex]
We can identify that:
[tex]10 \times 10 = {10}^{2} [/tex]
[tex]( - n) \times ( - n) \times ( - n) = ( - n)^{3} [/tex]
Therefore,
[tex] {10}^{2} \times ( - n)^{3} [/tex]
