Description

Describe what this variable represents, and list any assumptions made about its value.

Can an exam override the value of this variable?

Generated value: `integer`

This variable doesn't seem to be used anywhere.

Advice

To simplify $(\var{a}x^\var{n})^\var{m}$ , we want to make use of the following 2 rules:

$(ab)^n = a^n b^n$ ;
$(a^n)^m=a^{n\times m}$ .

Applying rule 1:

$(\var{a}x^\var{n})^\var{m}=\var{a}^\var{m} (x^\var{n})^\var{m}.$

Then applying rule 2 to the $x$ -term and simplifying:

$\begin{split} (\var{a}x^\var{n})^\var{m} &\,= \var{a}^\var{m} x^{\var{n} \times \var{m}}\\ &\,= \var{a^m} x^\var{n*m}. \end{split}$
