Look at this:
[latex]10^{\frac{1}{3}}10^{\frac{1}{3}}10^{\frac{1}{3}}=10^{1}=10[/latex]
Since you add exponents to multiply: 1/3+1/3+1/3 = 1 you get 10 to the 1st power.
It should then seem obvious that if you took the exponent of 1 ad divided it by 3, you could get the cube root.
So, if i had a number raised to a power and I wnted to find the cube root, I would just divide the exponent by 3.
Now, it doesn't give me a number quite yet until you plug it into your calculator or use LOGS. I put LOGS ont he back burner until you learn how to deal with exponents.
Remember the simple rules.
The BASES must be the SAME. To multiply you add exponents. To divide, you subtract exponents. To take the nth root you divide the single exponent by n. A square root is dividing by 2 or raising to the 1/2 power.
So what happens when you have this?:
[latex](10^{2}){}^{3}[/latex]
[latex]10^{\frac{1}{3}}10^{\frac{1}{3}}10^{\frac{1}{3}}=10^{1}=10[/latex]
