Is the square root of 8 greater than, less than, or equal to 4 ?

Tom [10]

Answer:

√8 is less than 4

Step-by-step explanation:

We need to compare √8 and 4

To compare the numbers they should both be in the same format

√8 is not a perfect square so we'll put number 4 under root

4 = √4² = √16

Now we compare

√8 < √16

So √8 is less than 4
