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