Identify the closest perfect squares less than and greater than the radicand below, respectively

square{23}

a. 16 and 24

b. 16 and 25

c. 18 and 24

d. 20 and 25

The perfect squares from 1 to 25 are:

1^2 = 1

2^2 = 4

3^2 = 9

4^2=16

5^2=25

Then the perfect squares less than and greater than 23 are 16 and 24.

Addtiionally note that the question must be about √23 (instead of square 23), because the radicand is the quantity inside a radical.

Answer: the option b of the list.
