Math Problem Statement

Which two integers is √79 between?

Solution

To find which two integers 79\sqrt{79} is between, we need to determine the two consecutive integers such that the square of the smaller integer is less than 79, and the square of the larger integer is greater than 79.

Let's find the square roots of some integers close to 79:

\sqrt{64} = 8 \quad \text{(since 64 = 8^2)}

\sqrt{81} = 9 \quad \text{(since 81 = 9^2)}

Since 64<79<8164 < 79 < 81, 79\sqrt{79} must be between 8 and 9.

Thus, the correct answer is "8 and 9."
