Does a radical in its simplest from contain a radical in its 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)
What is 15.556 in simplest radical form?
