Question
For hook-up, determine whether there is a single repeater machine that will do the same work. If so, describe or draw it.
Solution
Using law of exponents, am × an = (a)m + n ...[∵ a is non-zero integer]
Hook-up machine can do the work = 23 × 32 = 8 × 9 = 72
So, it is not possible for a single machine to do the same work.
Since, (× 82) = 64 and (× 92) = 81
