Start with the given expression

The goal of simplifying expressions with square roots is to factor the radicand into a product of two numbers. One of these two numbers must be a perfect square. When you take the square root of this perfect square, you will get a rational number.

So let's list the factors of 24

Factors:
1, 2, 3, 4, 6, 8, 12, 24

Notice how 4 is the largest perfect square, so lets factor 24 into 4*6

Factor 24 into 4*6

Break up the square roots using the identity

Take the square root of the perfect square 4 to get 2

So the expression simplifies to

Check:
Notice if we evaluate the square root of 24 with a calculator we get

and if we evaluate we get

This shows that . So this verifies our answer
