Rationalise the denominator.
To eliminate the radical in the denominator.
when there is no radical in the denominator
The 6th radical is raising something to the 1/6 power, and the 5th radical is the 1/5 power. Dividing means you subtract the exponents, and 1/6-1/5 is -1/30. The answer would be 1/(30th rad of the term).
Rationalising the denominator.
by dividing the numerator by the denominator
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)
It is called rationalisation [of the denominator].
It is called rationalising the denominator.
"rationalizing" the denominator
It is called rationalising the denominator.
Dividing the numerator and denominator by a common factor is how you simplify a fraction.
by dividing the denominator from the numerator .
