Question 160(v)

For each hook-up, determine whether there is a single repeater machine that will do the same work. If so, describe or draw it.

Answer 1

Using law of exponents, $a^m\times a^n=(a{)}^{m+n}$ [$\because$ a is non-zero integer]
Hook-up machine can do the work = ${12}^2\times {12}^3={12}^6[\because a^m\times a^n=(a{)}^{m+n}]$
So, $(\times {12}^5)$ machine can do the same work.
Diagram of $\times {12}^5$ single machine.
