Question 95209
Taking the 6th root of something is the same as raising it to the power or exponent {{{1/6}}}
.
So taking the 6th root of {{{t^2}}} is the same as raising it to the exponent {{{1/6}}}.
.
This can be written as follows:
.
{{{(t^2)^(1/6)}}}
.
Now you can apply the power rule of exponents. This rule says that when you have a term with
an exponent and you raise that term to an exponent, you multiply the two exponents.
.
In this case, when you have:
.
{{{(t^2)^(1/6)}}}
.
you multiply the exponent {{{2}}} times the exponent {{{1/6}}} and the product becomes the
new exponent for t. 
.
So we have as the new exponent for t the product: {{{2*(1/6) = 2/6 = 1/3}}} and the answer
becomes:
.
{{{t^(1/3)}}}
.
Hmm. It appears as if the 1 in the numerator of the exponent is clipped off a little.
Hopefully this doesn't confuse you. But this exponent of 1/3 just tells you to find the 
third root (or cube root) of t. And this can be written as:
.
{{{root(3, t)}}}
.
Hope this helps you to understand the problem along with providing you some information
about the meaning of fractional exponents and how to apply the power rule for exponents.
