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.
To eliminate the radical in the denominator.
The radicand is the value under the radical symbol.
No negative number can have a real square root.When you acquire enough math to work with imaginary numbers,you'll be able to express the square root of -52 as j7.2111 (rounded).
Radical (3x) = radical(x) * radical(3).
-3*radical(2)*radical(50) = -3*radical(2*50) = -3*radical(100) = -3*10 = -30
No, you can also use conjugates with more than one radical term. For example, if the denominator is root(2) + root(3), you can use the conjugate root(2) - root(3) to rationalize the denominator.
Yes. For example, the conjugate of (square root of 2 + square root of 3) is (square root of 2 - square root of 3).
Yes, you can.
You multiply the numerator and the denominator by the "conjugate" of the denominator. For example, if the denominator is root(2) + root(3), you multiply top and bottom by root(2) - root(3). This will eliminate the roots in the denonimator.
If you are referring to 1/sqrt7 then you multiply the numerator and denominator by sqrt7 over sqrt7. 1 = (1)sqrt7 = sqrt7 sqrt7 (sqrt7)sqrt(7) 7
To eliminate the radical in the denominator.
when there is no radical in the denominator
Rationalise the denominator.
Rationalising the denominator.
You can rationalize the denominator by multiplying this fraction by a fractional form of one in radical form. 3/sqrt(2) * sqrt(2)/sqrt(2) = 3sqrt(2)/2 ----------------
No. One of the rules for "simplest form" is that there may be no radical in the denominator. To fix this, multiply top and bottom of the fraction by the radical denominator. For example, ( 1 / √2) = (1 / √2)(√2 / √2) = (√2 / 2)
