Question

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

a (× 5⁹⁹) machine followed by a (5^–100) machine.

Answer 1

(× 5⁹⁹) machine followed by a (×(5)^–100) machine.

So, it produces `5^99 xx 1/5^100 = 1/5`

Hence, `(xx 1/5)` single machines can do the same job as the given hook-up.
