Answer:
multiply the number within parenthesis by itself the number of times equivalent to the exponent.
for example
1) 6^3 = 6*6*6 = 216
2) 4^2 = 4*4 = 16
3) 9^3 = 9*9*9 = 729
4) 8^3 = 8*8*8 = 512
5) 3^3 = 3*3*3 = 27
6) 2^3 = 2*2*2 = 8
7) 7^3 = 7*7*7 = 343
8) 5^3 = 5*5*5 = 125

10) out of frame
11) 9^2 = 9*9 = 81
12) 4^2 = 4*4 = 16
13) 12^2 = 12*12 = 144
14) 6^2 = 6*6 = 36
15) 10^2 = 10*10 = 100
16) 5^2 = 5*5 = 25
17) 3^3 = 3*3*3 = 27
18) 10^3 = 10*10*10 = 1000
