Rational Exponents And Radicals Examples With Solutions

Rational Exponents And Radicals Examples With Solutions Given an expression with a rational exponent write the expression as a radical Determine the power by looking at the numerator of the exponent Determine the root by looking at the denominator of the exponent Using the base as the radicand raise the radicand to the power and use the root as the index

Square roots are most often written using a radical sign like this 4 4 But there is another way to represent them You can use rational exponents instead of a radical A rational exponent is an exponent that is a fraction For example 4 4 can be written as 41 2 4 1 2 Dec 16 2022 0183 32 Suppose we want to find a number p such that 8p 3 8 We will use the Power Property of Exponents to find the value of p 8p 3 8 Multiple the exponents on the left 83p 8 Write the exponent 1 on the right 83p 81 Since the bases are the same the exponents must be equal 3p 1

Rational exponents and radicals show up in a lot of places For example they re used in physics to calculate things like electrical resistance and wave frequencies They re also used in finance to calculate compound interest

Templates are pre-designed documents or files that can be utilized for numerous purposes. They can save effort and time by offering a ready-made format and design for creating various kinds of material.
