## How do you rationalize a denominator with radicals?

So, in order to rationalize the denominator, we need to get rid of all radicals that are in the denominator.

- Step 1: Multiply numerator and denominator by a radical that will get rid of the radical in the denominator.
- Step 2: Make sure all radicals are simplified.
- Step 3: Simplify the fraction if needed.

How To Solve Fractional Exponents?

- Rule 1: a1/m × a1/n = a. (1/m + 1/n)
- Rule 2: a1/m ÷ a1/n = a. (1/m – 1/n)
- Rule 3: a1/m × b1/m = (ab) 1/m
- Rule 4: a1/m ÷ b1/m = (a÷b) 1/m
- Rule 5: a-m/n = (1/a) m/n

**Is it OK to have a radical in the denominator?**

A convention of mathematics is that you don’t leave radicals in the denominator of an expression when you write it in its final form. A numerator can contain a radical, but the denominator can’t. The final expression may look more complicated in its rational form, but that’s what you have to do sometimes.

### How do you rationalize a denominator?

To rationalize a denominator, multiply the fraction by a “clever” form of 1–that is, by a fraction whose numerator and denominator are both equal to the square root in the denominator.

**Do you leave radicals in the denominator?**

A convention of mathematics is that you don’t leave radicals in the denominator of an expression when you write it in its final form. Thus we do something called rationalizing the denominator. This convention makes collecting like terms easy, and your answers will be truly simplified. A numerator can contain a radical, but the denominator can’t.

**What does it mean to rationalize denominator?**

Rationalize the Denominator. “Rationalizing the denominator” is when we move a root (like a square root or cube root) from the bottom of a fraction to the top.

## What does rationalizing the denominator mean?

Rationalizing the denominator is the process of moving any root or irrational number (cube roots or square roots) out of the bottom of the fraction (denominator) and to top of the fraction (numerator). The denominator is the bottom part of a fraction. This part of the fraction can not have any irrational numbers.
