What is rationalize a denominator?
process by which a fraction containing radicals in the denominator is rewritten to have only rational numbers in the denominator.
What is the process of eliminating a radical in the denominator of a fraction?
It is called rationalizing the denominator, and it is done by multiplying numerator and denominator by appropriate numbers. Note that if you do that, you will usually end up with radicals in the numerator. Examples: 1 / (square root of 2): Multiply numerator and denominator by the square root of 2. 1 / (square root of 2 + square root of 3): Multiply numerator and denominator by (square root of 2 - square root of 3).
Why can't you have a radical in the denominator?
Most teachers tell you to keep radicals out of the denominator because it is considered bad form and makes the number harder to understand at first glance. If/when you get to calculus however, this rule is completely ignored and you are expected to keep radicals in the denominators during most operations. So bottom line, if you pardon the pun, is radicals are perfectly fine in the denominator.
What is simplest radical form?
Simplest radical form means simplifying a radical so that there are no more square roots, cube roots, 4th roots and such left to find. It also means removing any radicals in the denominator of a fraction.
What is the fraction rule of exponents?
Exponential fractions are basically the inverse of radicals. When you have an exponent use the denominator for the index of the radical and the numerator as the exponent to your base number. Example: 2 ^ 1/2 would be set up as the square root of 2 to the power of one. Solve the radical expression and that would be your answer.

Can you use conjugates to rationalize the denominator even when the denominator contains two radical terms?
Yes. The original denominator and its conjugate will form the factors of a Difference of Two Squares (DOTS) and that will rationalise the denominator but only if the radicals are SQUARE roots.
How To get rid of radicals in the denominator by multiplying the fraction by a helpful form of?
If there is only the radical, sqrt(b), in the denominator, the form of the fraction is sqrt(b)/sqrt(b).If the denominator is of the form a + sqrt(b) then the form of the fraction is [a - sqrt(b)]/[a - sqrt(b)].It is also possible to use [-a + sqrt(b)]/[-a + sqrt(b)], and this form may be preferred is a^2 < b.
A method used to eliminate radicals from the denominator of a fraction?
That is called "rationalizing the denominator". It consists of multiplying the numerator and the denominator by specific terms, which include square roots. Examples:* If the denominator is root(2) (that is, the square root of 2), multiply numerator and denominator by root(2). * If the denominator is root(2) + root(3), multiply numerator and denominator by root(2) - root(3).

Does The property of radicals for quotients states that the square root of a fraction is the square root of the denominator over the square root of the numerator?
its false apex :)

Can radicals can be written as fraction?
Sometimes, yes. Sqrt(0.25) = 0.5 = 1/2
How do you evaluate a radical?
There are three steps on how to evaluate a radical. Some of the step-by-step instructions are multiply two radicals with the same index number by simply multiplying the numbers beneath the radicals, divide a radical by another radical with the same index number by simply dividing the numbers inside, and simplify large radicals using the product and quotient rules of radicals.

What is meant by acidic radicals?
electronegative radicals are anions or acid radicals.
