Rational exponents can be expressed as radicals, that is, am/n=n√am. For example, we can write the square root of 5 as a rational exponent as well as in radical form: √5 = 51/2 What are Positive Rational Exponents? Positive rational exponents are expressed with positive exponents. For...
These examples help us model a relationship between radicals and rational exponents: namely, that the nthnth root of a number can be written as either n√xxn or x1nx1n.Radical Form Exponent Form √xx x12x12 3√xx3 x13x13 4√xx4 x14x14 … … n√xxn x1nx1nIn the table above, ...
2. Students will know and be able to evaluate expressions with rational exponents. A rational exponent does not have to be of the form 1/n. Other rational numbers such as 3/2 can also be used as exponents. You can use the properties of exponents to evaluate or simplify expressions involvi...

What is a rational (or fractional) exponent? A rational (that is, a fractional) exponent is a power that is expressed as a fraction, and which represents a radical. For instance, the expression 813831 means "the cube root of eight", or 8 338, which is 2. MathHelp.com Rational...
