Taking the 6th root of something is the same as raising it to the power or exponent 1%2F6
.
So taking the 6th root of t%5E2 is the same as raising it to the exponent 1%2F6.
.
This can be written as follows:
.
%28t%5E2%29%5E%281%2F6%29
.
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:
.
%28t%5E2%29%5E%281%2F6%29
.
you multiply the exponent 2 times the exponent 1%2F6 and the product becomes the
new exponent for t.
.
So we have as the new exponent for t the product: 2%2A%281%2F6%29+=+2%2F6+=+1%2F3 and the answer
becomes:
.
t%5E%281%2F3%29
.
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%283%2C+t%29
.
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.
