Solved by pluggable solver: Simplifying Square Roots (whole numbers only)
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 500

Factors:

1, 2, 4, 5, 10, 20, 25, 50, 100, 125, 250, 500



Notice how 100 is the largest perfect square, so lets factor 500 into 100*5





Factor 500 into 100*5



Break up the square roots using the identity



Take the square root of the perfect square 100 to get 10



So the expression simplifies to



----------------------------
Check:

Notice if we evaluate the square root of 500 with a calculator we get





and if we evaluate we get





This shows that . So this verifies our answer
