Can you show me how to do these?

27exponent2/3

AND

2exponent-3 + 4exponent -1
OVER
2exponent-3
 
\(\displaystyle 27^{2/3} = \sqrt[3]{{27^2 }}\)


when you have a constant or vaiable raised to a fration like above the denominator of the fraction becomes the index and the numerator hangs on to the constant or variable inside the radical.
 
What about

2exponent-3 + 4exponent -1
OVER
2exponent-3

Thanks a ton already, its helped alot.
 
well this is whats going on if I interpreted your problem right

\(\displaystyle \frac{{2^{ - 3} + 4^{ - 1} }}
{{2^{ - 3} }} = \frac{{\frac{1}
{{2^3 }} + \frac{1}
{{4^1 }}}}
{{\frac{1}
{{2^3 }}}}\)


if you have something raised to a negative exponet you drop it down to make is a positive one. As you study these you will learn rules that allow you to do these faster.
