This algebra video tutorial explains how to divide radical expressions with variables and exponents. Lean how to divide rational expressions with a radical in the denominator. Divide dividend by number under the radical.

When dividing radical expressions use the quotient rule. Theres a similar rule for dividing two radical expressions. The radical symbol denotes calculating the nth n t h root of a value which is the value that can be raised to the nth n t h power and simplifies to the value under the radical symbol.

To divide rational expressions with a radical in the denominator we rationaliz. For all real values a and b b 0. Then simplify the result.

Thats a mathematical symbols way of saying that when the index is even there can be no negative number in the radicand but when the index is odd there can be. 225 x 5 225 5. It contains plenty of examples and practice problems.

How Do You Divide Radicals. That would be true for multiplying square root of 3 times square root of 7 is equal to the square root of 3 times 7. Conjugates look like this.

A common way of dividing the radical expression is to have the denominator that contain no radicals. Remember that when we multiply radicals with the same type of root we just multiply the radicands and put the product under a radical sign. 6 sqrt6 6.

When dividing radicals with the same index divide under the radical and then divide in front of the radical divide any values multiplied times the radicals. Dont get that stuff confused in your head. In this case 22 divided by 5 225 Yep sometimes you wind up with a fraction or a decimal.

Rationalizing is the process of starting with a fraction containing a radical in its denominator and determining fraction with no radical in its denominator. Learn how to find the cube root of rational expressions. So when were looking at these sums or differences of radical expressions that have different radicands were going to be coming across what we call conjugates.

When dividing radicals with the same index divide under the radical and then divide in front of the radical divide any values multiplied times the radicals.

You have just rationalized the denominator. Other than that you just have to leave it because you cannot combine radicals and whole numbers. If n is odd and b 0 then.

If you have one square root divided by another square root you can combine them together with division inside one square root. Subsequently question is what is. If n is even and a 0 b 0 then.
