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

<em>To compare the numbers they should both be in the same format</em>

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

  • 4 = √4² = √16

<u>Now we compare</u>

  • √8 < √16

So √8 is less than 4
