# Identify Simple Exponents

In this worksheet, students will use simple exponents.

Key stage:  KS 3

Curriculum topic:   Number

Curriculum subtopic:   Understand Integer Powers/Real Roots

Difficulty level:

#### Worksheet Overview

We use exponents as a shorthand way of writing calculations such as:

31 x 31 x 31 x 31 x 31

This is a multiplication of the base number 31 by itself five times and so can be written as:

315

5 is the exponent

NB This is not the same as 31 x 5

When there are two base numbers, such as 31 and 41, we deal with them separately.

31 x 31 x 31 x 41 x 41

This is a multiplication of the base number 31 by itself three times and the base number 41 by itself twice, so can be written as:

313 x 412

Let's have a go at some questions now.
