Gap-fill

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

By using the definition of the square root you should see that $(\sqrt{q})^2=q$ .

By using index laws you should see that $(q^{1/2})^2=q$ .

The above equations imply that $\sqrt{q}$ can also be written as Unnamed gap.

Note: If you want to use a fraction as a power you should use brackets to surround your power, for example, type 12^(2/3) for $12^\frac{2}{3}$ .
