For each hook-up, determine whether there is a single repeater machine that will do the same work. If so, describe or draw it.
Using law of exponents, am×an=(a)m+n [∵ a is non-zero integer] Hook-up machine can do the work = 122×123=126 [∵ am×an=(a)m+n] So, (×125) machine can do the same work. Diagram of ×125 single machine.
Find a single repeater machine that will do the same work as each hook-up.
