How do you convert a rational exponent to radical form?

Back

To convert a rational exponent a^(m/n) to radical form, it can be expressed as the n-th root of a raised to the m power: a^(m/n) = n√(a^m).

How can you multiply two expressions with rational exponents?

Back

To multiply two expressions with rational exponents, you can add the exponents if the bases are the same: a^(m/n) * a^(p/q) = a^((mq + np)/(nq)).
