What is the first step in estimating the square root of a non-square number?

• Divide the number by 2.

• Add 10 to the number.

• Find the square numbers on either side of the given number.

• Multiply the number by itself.

If you are estimating the square root of 77, which two square numbers should you consider?

• 49 and 64

• 64 and 81

• 81 and 100

• 36 and 49

Why is the estimated square root of 77 closer to 9 than to 8?
