Dividing square roots is essentially simplifying a fraction. Of course, the presence of square roots makes the process a little more complicated, but certain rules allow us to work with fractions in a relatively simple way. The key thing to remember is that you must divide coefficients by coefficients, and radicands by radicands.
Step 1. Rewrite the expression by combining the rational and irrational numbers into two distinct quotients. Step 2. Combine the square roots under 1 radicand.
In this lesson, students learn to divide square roots by dividing the numbers that are inside the radicals. Students also learn that if there is a square root in the denominator of a...
Divide Square Roots. We know that we simplify fractions by removing factors common to the numerator and the denominator. When we have a fraction with a square root in the numerator, we first simplify the square root. Then we can look for common factors.

To divide square roots, we first need to write the division as a fraction with a square root in the numerator and denominator, and then we can simplify the fraction by multiplying the numerator and denominator by the square root of the denominator.
Dividing Square Roots. When dividing with square roots, we must treat coefficients, numbers within our base, and variables within our base all differently. Lets begin with a simple problem involving only numbers in our bases. Example: √150 / √6. Instead of using two separate square roots, make this one square root with division occurring inside it.
To rationalize a denominator with a square root, we use the property that \((\sqrt{a})^{2}=a\). If we square an irrational square root, we get a rational number. We will use this property to rationalize the denominator in the next example.

There is a fun method for calculating a square root that gets more and more accurate each time around: a) start with a guess (let's guess 4 is the square root of 10) b) divide by the guess (10/4 = 2.5) c) add that to the guess (4 + 2.5 = 6.5) d) then divide that result by 2, in other words halve it. (6.5/2 = 3.25)
