This week in math I learned how to write a radical as a power and vice versa. If you’re starting with a radical, the number under the root sign is the base, the exponent on that number is the numerator in the exponent (remember, there is always an invisible 1) the index of the radical is the denominator of the exponent, and now you have a power. If you’re starting with a power, the base is the sign under the root, the exponent’s numerator is the exponent on the number under the root sign, and the exponent’s denominator is the index of the radical, and you have now turned a power into a radical.
