This is a free lesson from our course in Algebra II
In this section you'll learn how to calculate number raised to fractional exponents. You will find some examples with solution,
and the instructor explains all that with the help of audio, video presentation
and in own hand writing. Fractional exponents obey the same laws as integral exponents.
To calculate a number raised to a fractional exponent,
we take the denominator roots and raise that to the numerator power.
For example,
64^{2/3} =(^{3}64)^{2}=(4)^{2}=16
or you can do it as 64^{2/3} =(^{3}64^{2})=(^{3}4096)=16.
Consider one more example, 32^{4/5}=(^{5}32)^{4}=(2)^{4}=
16.
