Writing , , and with Rational Exponents
Convert three radical expressions that have compound radicands (products of numbers and variables) into rational exponent form, using .
ⓐ : No index is shown, so the index is . The entire radicand becomes the base, enclosed in parentheses, and the index becomes the denominator of the exponent: .
ⓑ : The index is , so the denominator of the exponent is . The entire radicand is the base: .
ⓒ : The index is , so the denominator of the exponent is . The radicand becomes the base raised to the power. The coefficient in front of the radical stays as a factor outside the exponential expression: .
When the radicand is a product of multiple factors, parentheses are essential to indicate that the entire product — not just one factor — is raised to the fractional power. A coefficient that multiplies the radical from outside remains as a separate multiplier in the rational exponent form.
