Question

Find a single machine that will do the same job as the given hook-up.

a (× 2⁴) machine followed by `(xx (1/2)^2)` machine.

Answer 1

(× 2⁴) machine followed by `(xx (1/2)^2)` machine.

So, it produces `2 xx 2 xx 2 xx 2 xx 1/2 xx 1/2 = 4`

Hence, (× 2²) single machine can do the same job as the given hook-up.
