Haley’s work evaluating (-2)8 squared is shown below. Which statement best describe Haley’s first error?

A. She used the wrong number as a repeated factor and should have

B. She used the wrong number as a repeated factor and should have evaluated

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. its D on edge

D

Step-by-step explanation:

she made a sign error when multiplying and should have had 256 as an answer

answer: solve 5\cdot 2^x=2405⋅2  

x

=2405, dot, 2, start superscript, x, end superscript, equals, 240.

solution

to solve for xxx, we must first isolate the exponential part. to do this, divide both sides by 555 as shown below. we do not multiply the 555 and the 222 as this goes against the order of operations!

\begin{aligned} 5\cdot 2^x& =240 2^x& =48 \\ \end{aligned}  

5⋅2

=240

=48
