8 to the power (2/3) equals 4.
(4^5)x(4^-3)=(4^2)=16
The browser used by Answers.com is not up to the formatting, but consider 2 to the power 3 to the power 4. (2 to the power 3) to the power 4 = 8 to the power 4 = 4096 while 2 to the power (3 to the power 4) = 2 to the power 81 = 3.9*10154 (approx). These two values are not equal and this, therefore, acts as an example showing that exponentiation is not associative.
3 to the third power (3^3) is equal to 27. 4 to the third power (4^3) is equal to 64. Combining the 2 answers (27*64) we have 1968.
