The words Squared and Square Root are opposites.
You should know that 6 squared = 36 because 6 x 6 = 36
We write this as 62 = 36
And so the square root of 36 = 6
We write this as √36 = 6
Example
Work out √49 and √4900
Answer
√49 = 7 because 72 = 49
√4900 = 70 because 702 = 7 x 10 x 7 x 10 = 72 x 102
