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
What is the square route of 24
3 answers
24 = 4 * 6
so
2 sqrt(6)
which is about
4.898979486
so
2 sqrt(6)
which is about
4.898979486
Exactly Thanks Damon;)
