# For the following repeater machines, how many times the base machine is applied and how much the total stretch is?

**Solution:**

Given, the figure represents a repeater machine.

We have to find the total stretch.

From the machine a,

Stretch = 100²

Total stretch = × 100² = 10000

It is two times the base machine.

From the machine b,

Stretch = 7⁵

Total stretch = × 7⁵ = 16807

It is five times the base machine.

From the machine c,

Stretch = 5⁷

Total stretch = × 5⁷ = 78125

It is seven times the base machine.
