Question

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

Sum

Solution

Using law of exponents, am × an = (a)m + n  ...[∵ a is non-zero integer]

Hook-up machine can do the work = `2^2 xx (1/3)^3 xx 5^4`

= `4 xx 1/27 xx 625`

= `2500/27`

= 92.59

So, it is not possible for a single machine to do the same work.
