Question 160(iv)

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's work = $(0.5{)}^2\times (0.5{)}^3=(0.5{)}^5$ [$\because a^m\times a^n=a^{m+n}$ ]
So $\times (0.5{)}^5$ machine can for the same work.
Diagram of single $\times (0.5{)}^5$ machine.
