?

anonymous · Answer

its d:0

anonymous · Answer

A variable to the power of 0 equals 1.
A variable to the power 1 equals the variable itself only.
A number to the negative power gives a fraction , where the denominator is raised to the power as a positive value, that is:$$b ^{-2}=\frac{ 1 }{ b ^{2} }$$

anonymous · Answer
