Worksheet Overview

QUESTION 1 of 10

The words Squared and Square Root are opposites.


You should know that 0.3 squared = 0.09 because 0.3 x 0.3 = 0.09

We write this as 0.32 = 0.09


And so the square root of 0.09 = 0.3

We write this as √0.09 = 0.3



Work out √0.49 and √0.0001



√0.49 = 0.7 because 0.72 = 0.49


 √0.0001 = 0.01 because 0.01= 0.01 x 0.01 = 0.0001
