If possible, find a hook-up of prime base number machine that will do the same work as the given stretching machine. Do not use (× 1) machines. (figure b)
Solution:
Given, the figure represents a single machine.
We have to find a hook-up of prime base number machine that will do the same work as the given stretching machine.
Total work of the single machine = ×99
The prime factors of 99 = 11 × 9
We know, 9 = 3²
=11 × 3²
Now, machines with base 11, power 1 and base 2, power 2 can be hooked up to produce the same work.
Therefore, prime base machines hooked up are (×11¹) and (×3²)
✦ Try This: If possible, find a hook-up of prime base number machine that will do the same work as the given stretching machine. Do not use (× 1) machines.
