When you're dealing with rational exponents, the numerator is the power, the denominator is the root. You can start off with the power or the root, it doesn't matter which one.

The 3rd root of 8 is 2, and 2 to the 4th is 16. 8 to the power of 4/3 is 16.

Just like before, the 3rd root of 8 is 2, and 2^1 is obviously 2.

So what you get is 16-2, which is 14.

8^4/3-8^1/3=14
