Published on April 10, 2026
Learn how to simplify the square root of 64 to its simplest radical form, which results in an integer.
Question
Answer
For a square root, simplest radical form means that the radicand (the number inside the square root) has no perfect square factors other than 1. If the radicand is itself a perfect square, then the square root can be simplified to an integer.
We need to find a number that, when multiplied by itself, equals 64.
We can test perfect squares:
So,
The result is 8, which is an integer. Integers do not have a radical sign, so they are considered to be in simplest radical form. Alternatively, we can think of 8 as
