Directions: Determine if the expression is a perfect square. If not, determine the two perfect
squares that the square root lies between.
(^) √ 9
Solution:
32 = 3⋅3 = 9, therefore
√^9 =√^3 ⋅^3 = 3^
When creating a perfect square with an area of 9, the measurement of the length needs to be 3 and
the measurement of the width needs to be 3.
√ 5
Solution:
5 is not a perfect square and this can be proved since a square cannot be built with an area of 5.
Since √ 5 is not a perfect square, the answer √ 5 lies between 2 and 3.
