To identify the whole number that has a square root between 3 and 4 I found the perfect square of the two consecutive numbers and chose the whole number between the two perfect squares.


12 will have a value between 3 and 4
YOU KNOW THAT THIS IS YOUR ANSWER BECASUE 3 GROUPS OF 4 IS 12.
Question 3
Jason is doing his math homework he has to find the square root of 10.He presses 10 on his calculater and the screen display's 3.1627766. However when 3.1627766 is mutiplied by itself the answer is not 10, explain.
The answer is because 10 is not a perfect square the value shown on the calculator is only an approximation.
