To eliminate the radical in the denominator.
when there is no radical in 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)
15.556 is a rational number, so there is no sensible 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.
rational
Conjugates are often used in radical problems to simplify expressions and remove radicals from denominators. When dealing with a fraction that has a radical in the denominator, multiplying both the numerator and denominator by the conjugate of the denominator allows for the application of the difference of squares formula, which eliminates the radical. This technique simplifies calculations and makes it easier to work with rational expressions. Additionally, using conjugates can help in solving equations involving radicals more efficiently.
Rationalise the denominator.
Rationalising the denominator.
No, it is not.
It is called rationalisation [of the denominator].
It's already in simplest radical form.
