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.

what's the question?

step-by-step explanation:

there is no question.

the 3rd on is correct

step-by-step explanation:

the solution of the equation is 2.23 ⇒ answer b

step-by-step explanation:

* lets revise the meaning of exponential function

- the form of the exponential function is y = ab^x, where a ≠ 0, b > 0 ,  

  b ≠ 1, and x is any real number

- it has a constant base b

- it has a variable exponent x

- to solve an exponential equation, take the log or ln of both sides,  

  and solve for the variable

* lets solve the problem

∵

- the base is 7 and the exponent is x

- insert ㏑ in both sides

∴

- use the rule

∴ x ㏑(7) = ㏑(77)

- to find x divide both sides by ㏑(7)

∴

* the solution of the equation is 2.23 to the nearest 2 decimal places
