Question
Find a single repeater machine that will do the same work as hook-up.
✓
Answer
Using law of exponents, $\left(a^m \times a^n=a^{m+n}\right)$$[\therefore$ a is non-zero integer$]$
Repeator machine can do the work is equal to $7^{10}× 7^{50}×7^{1}= 7^{61}$.
so, $(x7^{61})$ single machine can do the same work.
