Evaluate numerical expressions with unit-fraction exponents or radicals, and convert between the two forms of representations.

An overview of fractional (i.e., rational) exponents, including an example and practice problems with solutions.

Rewrite some elaborate exponential expressions that involve fractional exponents and radicals. Students receive immediate feedback and have the opportunity to try questions repeatedly, watch a video or receive hints.

The purpose of the task is to connect properties of fractional exponents with ordering of real numbers. Aligns with N-RN.A.2.

A tutorial including exercises on rational exponents. The materials can also be downloaded in PDF format.

Rewrite exponential expressions (where the exponent can be a fraction) using the properties of exponents. Students receive immediate feedback and have the opportunity to try questions repeatedly, watch a video or receive hints.

Rewrite exponential expressions (where the exponent can be a fraction) using the properties of exponents.

The goal of this task is to use properties of exponents for whole numbers in order to explain how expressions with fractional exponents are defined. Aligns with the N-RN.A.1 standard.
