Haley's work evaluating (-2)⁸ is shown below.

(-2)⁸ = (-2)(-2)(-2)(-2)(-2)(-2)(-2)(-2) = -256

Which statement BEST describes Haley's first error

• She used the wrong number as a repeated factor and should have evaluated -2 x 2 x 2 x 2 x 2 x 2 x 2 x 2.

• She used the wrong number as a repeated factor and should have evaluated - (8 x 8).

• She misinterpreted the exponential form and should have multipled -2 and 8.

• She made a sign error when multiplying and should have had 256 as the final answer.
