Question 26605
fractional exponents are another way of writing roots:



{{{sqrt(2x)}}} is the same as {{{(2x)^(1/2)}}}


and so nth root of say x is {{{(x)^(1/n)}}}


Is this an easier way of understanding roots? Shrugs here...it is just another weapon in your maths arsenal to solve questions. Sometimes keeping roots and sometimes keeping fractional exponents will help.
