a to the b power means b lots of a, all multiplied together. Thus, 203 or "20 to the 3rd power" can be rewritten as 20x20x20. If this value is calculated it comes out as 8,000. Thus 20 to the 3rd power can be simply expressed as 8,000.
= 20^3
2431/3 = cuberoot(243) = 6.24 approx
202 / 502 = (20/50)2 = (2/5)2 = 4/25 = 0.16

It means find the value of the expression. It cannot be simplified in the way that algebraic expressions usually are.
(2^2)^3= 2^6 = 64 your welcome, look in your textbook. ;0
Yes. 5 and 20 are divisible by 5, so you can simplify 5/20 to 1/4.
