Estimate

100

What 2 integers is √40 in between?

6 and 7 

√40 is between √36 and √49, which are 6 and 7

200

Estimate √90.

Approximately 8.5

√90 is about halfway between √81 and √100

so √90 is about halfway between 9 and 10

300

Which number has a square root between 4 and 5?

A. 4.5        B. 9       C.  20       D. 27

C. 20

because √20 is between √16 and √25

400

Estimate √15.

Approximately 3.8 or 3.9

because √15 is between √9 and √16 but much closer to √16 or 4.

500

Estimate ∛10.

It is between ∛8 and ∛27, which are 2 and 3.

So approximately 2.2 because 10 is closer to 8.
