The square root of 3y divided by the square root of x?

The fraction must be rationalized. Since it is the square root of x in the denominator, you are going to multiply the numerator and denominator by the square root of x. For simplicity of the problem, root will take the place of the symbol for square root: root(3y)/root(x) root(3y)*root(x)/root(x)*root(x) root(3xy)/x The simplified answer is going to be the square root of 3xy divided by x. Hope that helped.


How do you rationale the denominator?

Depends on the situation. You usually have to multiply numerator and denominator by some number or expression. Examples: 1 / square root of 2 Here, you have to multiply numerator and denominator by the square root of 2. 1 / (square root of 2 + square root of 3) Here, you have to multiply numerator and denominator by (square root of 2 - square root of 3).


Can 3 divided by the square root of 2 be simplified?

In a way. You can multiply top and bottom by the square root of 2. This will not exactly make the expression simpler, but you'll get rid of the square root in the denominator (and transfer it to the numerator); this is considered to be the standard form for expressions which involve square roots. In other words, there should be no square roots in the denominator.


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).

What is 3 over the square root of 5?

You can get a decimal approximation with a calculator, with Excel, etc. But if you want to keep it as a square root, the "standard form" is considered to be one that has no square roots in the denominator. In this case, to get rid of the square root in the denominator, you multiply both numerator and denominator by the square root of 5, with the following result: 3 / root(5) = 3 root(5) / root(5) x root(5) = 3 root(5) / 5 That is, three times the square root of 5, divided by 5.


How do you rationalize the denominator in this expression 2 divided by the square root of 3 plus the square root of 2?

Multiply everything by the square root of 3 minus the square root of 2 and then times that by 100 - 72 and divide that by 5


How do you find the square root of 625 over 36?

The square root of a fraction is(square root of the numerator) divided by (square root of the denominator).sqrt(625) = 25sqrt(36) = 6sqrt( 625/36 ) = 25/6 = 41/6

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).

Can you rationalize the denominator using conjugates even when the denominator contains two radical terms?

Yes. For example, the conjugate of (square root of 2 + square root of 3) is (square root of 2 - square root of 3).
