# What will the following machine do to a 2 cm long piece of chalk?

**Solution:**

Given, the figure represents a machine.

We have to find the work that the machine will do to a 2 cm long piece of chalk.

From the figure,

Input = 2 cm

Machine work = ×1^{100}

We know, 1^{100} = 1

So, the work done by the machine = 1

Output = 2 × 1

= 2 cm

Therefore, the chalk piece remains the same.
