When you find square roots, the symbol for that operation is a radical, which looks like this: When changing from radical form to fractional exponents, remember these basic forms: The nth root of a can be written as a fractional exponent with a raised to the reciprocal of that power. When the nth root of. is taken, itâs raised to the 1/n power. When a power is raised to another power, you multiply the powers together, and so the m (otherwise written as m/1) and the 1/n are multiplied together.
