What two integers does √18 fall between?

A 2 and 3

B 4 and 5

C 6 and 8

D It is exactly 3.5

E It is exactly 9

B. 4 and 5

Step-by-step explanation:

One way to do this is to take integers and square them:

42=16

52=25

Keep in mind, however, that we can also do this on the negative side:

(-4) 2=16

(-5) 2=25

And so if we can limit the answer to positive integers, we have one set. But if we allow negative integers, we have 2 sets.
