Question
For hook-up, determine whether there is a single repeater machine that will do the same work. If so, describe or draw it. 
✓
Answer
Using law of exponents, $\left(a^m \times a^n=a^{m+n}\right)[\because a$ a is non-zero integer$]$
Hook-up machine can do the work $=2^3 \times 3^2=8 \times 9=72$
So, it is not possible for a single machine can do the same work.
Since, $\left(x 8^2\right)=64$ and $\left(x 9^2\right)=81$.
