A half ( 20 = 1, so 2 to the (0 - 1) = 1/2)
Three fourths to the negative first power is 1.33333333333
-(3^(-2)) = -0.111111111
5.3 times ten to the negative first power is 0.53
Two and five tenths to the negative third power equals 0.064

Five halves to the negative 2nd power is 0.16
One half to the negative first power is equal to the reciprocal of one half raised to the first power. The reciprocal of one half is two, so (1/2)^(-1) = 1 / (1/2) = 1 * 2 = 2.
negative eight plus two times four to the second power
-2 to the first power = -2^1. -2^1 = -2*1. -2*1 = -2. The answer is negative two.
2^(-2) = 0.25
