Question statement

Trekk sammen uttrykkene.

Vi har disse reglene, som gjelder for alle tall $b$ og alle positive tall $x$ og $y$ :

$\begin{align}\log_a(x^b)&=b\log(x)\\ \log_a(x)+\log_a(y)&=\log_a(xy)\text{,}\\ \log_a(x)-\log_a(y)&=\log_a\left(\frac{x}{y}\right)\text{.} \end{align}$

Give any introductory information the student needs.

			Name	Type	Generated Value

			x1	list	List of 8 items
			y1	integer	3
