Javier estimates the square root of 18 in the following way:

18−−√=29–√=2∗3=6
18=29=2∗3=6



Explain why her reasoning is incorrect.

Without using a calculator, the square root of 18 will be between what two values (remember to look for perfect squares/perfect square roots)? Show your reasoning. You do not need to find the decimal equivalent of the root.

4x4 = 16

5x5 = 25

so √18 is between 4 and 5. closer to 4
