**Between Which Two Consecutive Whole Numbers Does $\sqrt{39}$ Lie, and Why?**

Understanding the Problem

To determine between which two consecutive whole numbers $\sqrt{39}$ lies, we need to find the square root of 39 and then identify the two consecutive whole numbers that it falls between.

The Square Root of 39

The square root of 39 is a number that, when multiplied by itself, equals 39. In mathematical terms, it is represented as $\sqrt{39}$ . To find the square root of 39, we can use a calculator or estimate it by finding the two perfect squares that 39 falls between.

Perfect Squares and the Square Root of 39

Let's find the two perfect squares that 39 falls between. We know that $5^2 = 25$ and $6^2 = 36$ . Since 39 is greater than 25 and less than 36, we can conclude that the square root of 39 lies between 5 and 6.

Why Does $\sqrt{39}$ Lie Between 5 and 6?

$\sqrt{39}$ lies between 5 and 6 because 39 falls between $5^2 = 25$ and $6^2 = 36$ . This is a fundamental property of square roots, where the square root of a number lies between the two consecutive whole numbers whose squares it falls between.
