Final Check for Understanding

(Teacher Checks Work)

Directions: Determine if the expression is a perfect square. If not, determine the two perfect

squares that the square root lies between.

1. √ 16

Solution:

42 = 4⋅4 = 16 , therefore

√ 16 =√ 4 ⋅ 4 = 4

2. √ 29

Solution:

29 is not a perfect square.

29 lies between 25 and 36 , which are both perfect squares.

Since √ 29 is not a perfect square, √ 29 lies between 5 and 6.
