(45) x (43) = 48
4 raised to the first power is just 4.
4^3√32-3^3√108+^3√256
-6.285714286x10^11
9000000000 / 3000 = 9000000/3 = 3000000 OR 3 x 106
i^1=i i^2=-1 i^3=-i i^4=1 and so forth 15 divided by 4 leaves a remainder of 3 i^3=-i
(2)-1/3 x (4)-1/3 = (2 x 4)-1/3 = (8)-1/3 = 1/81/3 = 1/2
You evaluate the power of the power first. For example, 4 to the power of (3 to the power of 2) is 4 to the power of 9 which is 262,144
