# Evaluating Powers (2)

In this worksheet, students evaluate powers.

Key stage:  KS 3

Curriculum topic:   Number

Curriculum subtopic:   Understand Integer Powers/Real Roots

Difficulty level:

### QUESTION 1 of 10

We read 37 as 3 to the power of 7 or as 3 to the 7.

Remember, to work out 3 x 3 x 3 x 3 x 3 x 3 x 3, we start at 3 and keep multiplying by 3 another six times......

3, 9, 27, 81, 243, 729, 2187

So 37 = 2187

Be careful

This has nothing really to do with the number 7 itself.

It is not the same as 3 x 7 = 21.

This would be the answer to 3 + 3 + 3 + 3 + 3 + 3 + 3.
