#### Worksheet Overview

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.
