Haley's work evaluating (-2)^8 is shown below.
(-2)^8 = (-)
= -256
which statement best describe haley's first error?
a) she used the wrong number as a repeated factor and should have evaluated -2x2x2x2x2x2x2x2.
b) she used the wrong number as a repeated factor and should have evaluated -(8x8).
c) she misinterpreted the exponential form and should have multiplied -2 and 8.
d) she made a sign error when multiplying and should have had 256 as a final answer.
