Take $ah \in aH$; then $ah = (ab^-1)bh \in bH$, since $ab^-1 \in H$ and $bh \in bH$. Conversely, take $bk \in bH$; then $bk = a( ab^-1 )k \in aH$, since $ab^-1 \in H$. then $ah = (ab^-1)bh \in bH$

Working through these exercises is crucial because the authors often include important definitions and results (like the Frattini Argument) within the problems rather than the main text.
