Question statement

Based on the definition of logarithms determine the following:

Give any introductory information the student needs.

			Name	Type	Generated Value

c	integer	12
power	integer	-11
ans1	integer	-132
mult	integer	-7
d	integer	-7
root	integer	5
square	number	9
ans4	number	3

Automatically regenerate variables?

Gap-fill

Ask the student a question, and give any hints about how they should answer this part.

Suppose $\log_b\left(a\right)=\var{c}$ . Evaluate $\log_b\left(a^\var{power}\right)$ = Unnamed gap.

Advice

Given the equation $\log(a^n)$ we can rearrange this as $n\log(a)$

As $\sqrt[n]{x}$ = $n^{\frac{1}{n}}$ , $\log(\sqrt[n]{a}) = \frac{\log(a)}{n}$

Give a worked solution to the whole question.
