Question 53382
For example, the rational exponent {{{x^(4/3) }}} is easier to write and work with than the radical expression {{{(root(3,x^4)) }}}.


For comparison, consider solving the following two equations, whose solution is x=27:


Radical sign:  
Solve {{{(root(3,x^4)) = 81}}}


Rational exponent:
Solve {{{x^(4/3) = 81}}}.
