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

(a) $\var{Q3aExpansion}$ = a

(b) $\var{Q3dExpansion}$ = b

Advice

(a) $\var{Q3aExpansion}=\var{expression(Q3aBase)}^\var{Q3aIdx}$

(b) $\var{Q3dExpansion}=\left(\frac{\var{Q3dBaseNum}}{\var{Q3dBaseDen}}\right)^{\var{Q3dIdx}}$

Give a worked solution to the whole question.
