Let us learn about simplified radical form
-->Simplified radical form is an expression which is under the symbol square root. The expression contains fraction, addition, multiplication, subtraction. The simplified radical form is to simplify the specified expression in very simplified form. The simplified radical form includes the symbol square root in the numerator but not in the denominator.
A radical is also in simplest form only when the radicand is not a fraction. 49 is a sq factor of 98, so the simplified radical would be seven times the square root of two or seven on the square root of 2. All exponents in the radicand should be less than the index. Any exponents in the radicand may have no factors in common with the index. No fractions appear under a radical. No radicals appear in the denominator of a fraction
