Haley’s work evaluating (Negative 2) Superscript 8 is shown below.

(Negative 2) Superscript 8 = (negative 2) (negative 2) (negative 2) (negative 2) (negative 2) (negative 2) (negative 2) (negative 2) = negative 256

Which statement best describe Haley’s first error?
She used the wrong number as a repeated factor and should have evaluatedNegative 2 times 2 times 2 times 2 times 2 times 2 times 2 times 2.
She used the wrong number as a repeated factor and should have evaluated Negative (8 times 8).
She misinterpreted the exponential form and should have multiplied –2 and 8.
She made a sign error when multiplying and should have had 256 as a final answer.

without parens, powers are done before subtraction.
-2^8 = -(2^8) = -256
(-2)^8 = +256
