print(math.pow( 2,      2   ) )     # 4.0
print(math.pow( 3,      2   ) )     # 9.0

print(math.pow( 0,      3   ) )     # 0.0
print(math.pow( 0.5,    0.3 ) )     # 0.8122523963562356
print(math.pow( -1,     4   ) )     # 1.0

print(math.pow( -0.5,   -2  ) )     # 4.0
print(math.pow( -2.0,   -2  ) )     # 0.25
