QUESTION 1:
2 -3 0.3 2/3 -1/4
For a start, everything to the power of 0 equals 1, so you can write 1 for everything in the top row.
Then, everything to the power of 1 equals itself, so for the 2nd row, write:
2, -3, 0.3, 2/3, -1/4
The rest of it is here:
2 ^ 2 = 4
2 ^3 = 8
2 ^4 = 16
2 ^5 = 32
-3 ^ 2 = -9
-3 ^ 3 = -27
-3 ^ 4 = -81
-3 ^ 5 = -243
0.3 ^ 2 = 0.09
0.3 ^ 3 = 0.027
0.3 ^ 4 = 0.0081
0.3 ^ 5 = 0.00243
2/3 ^ 2 = 0.22
2/3 ^ 3 = 0.074
2/3 ^ 4 = 0.025
2/3 ^ 5 = 0.008
(-1/4) ^ 2 = 0.0625
(-1/4) ^ 3 = (-0.016)
(-1/4) ^ 4 = 0.004
(-1/4) ^ 5 = (-0.00098)
Unfortunately I currently don't have time to help you on Questions 2 or 3, but I hope this helps! :)
