Question 160(iii)

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 = $2^2\times {\left(\frac{1}{3}\right)}^3\times 5^4=4\times \frac{1}{27}\times 625=\frac{2500}{27}=92.59$
So, it is not possible for a single machine to do the same work.
