### Theory:

Do you know what the mass of the earth is?
The number \(5\) is called the base, and the number \(2\) is called the exponent.

It is \(5,970,000,000,000,000,000,000,000\) kg!

Can you read this number?

These huge large numbers are difficult to read, understand and compare. To make these numbers easy to read, understand and compare, we use powers and exponents.

In this exercise, we will see what powers and exponents are:

Power is the product of multiplying a number by itself. It shows how many times the base is multiplied by itself.

The base number tells what number is being multiplied.

The exponent, a small number written above and to the right of the base number, tells how many times the base number is being multiplied.
