evaluate the expression for the given value of the variable

OpenStudy (anonymous):

\[\left| -4b-8 \right|+\left| \left| -1-b ^{2} \right| \right|+2b ^{3} \]

OpenStudy (anonymous):

b=-2

OpenStudy (solomonzelman):

\(\large\color{black}{ \displaystyle \left| -4b-8 \right|+\left| -1-b ^{2} \right|+2b ^{3} }\) you mean like this?

OpenStudy (solomonzelman):

without dobule bars.

OpenStudy (solomonzelman):

double* bars

OpenStudy (anonymous):

yes

OpenStudy (solomonzelman):

Then plug in -2 for b. \(\large\color{black}{ \displaystyle \left| -4(-2)-8 \right|+\left| -1-(-2) ^{2} \right|+2(-2) ^{3} }\)

OpenStudy (anonymous):

my final answer is 13

OpenStudy (solomonzelman):

I think that is incorrect.

OpenStudy (solomonzelman):

\(\large\color{black}{ \displaystyle \left| -4(-2)-8 \right|+\left| -1-(-2) ^{2} \right|+2(-2) ^{3} }\) \(\large\color{black}{ \displaystyle \left| 8-8 \right|+\left| -1-(-2) ^{2} \right|+2(-2) ^{3} }\) \(\large\color{black}{ \displaystyle \left| 0 \right|+\left| -1-(-2) ^{2} \right|+2(-2) ^{3} }\) \(\large\color{black}{ \displaystyle \left| -1-(-2) ^{2} \right|+2(-2) ^{3} }\)

OpenStudy (solomonzelman):

\(\large\color{black}{ \displaystyle \left| -1-(-2) ^{2} \right|+2(-2) ^{3} }\) \(\large\color{black}{ \displaystyle \left| -1-4 \right|+2(-2) ^{3} }\) \(\large\color{black}{ \displaystyle \left| -5 \right|+2(-2) ^{3} }\) \(\large\color{black}{ \displaystyle 5+2(-2) ^{3} }\) \(\large\color{black}{ \displaystyle 5+2(-8) }\)

OpenStudy (solomonzelman):

and on...

OpenStudy (solomonzelman):

and you then get a negative number, that I will give you.

OpenStudy (anonymous):

@SolomonZelman would you add 5 and 2 and then multiply 7 by -8

OpenStudy (anonymous):

@SolomonZelman and the answer would be -56?

OpenStudy (solomonzelman):

You first multiply.

OpenStudy (solomonzelman):

So it is `(-2)•8` And only then, you add 5

OpenStudy (anonymous):

-11?

OpenStudy (solomonzelman):

Yes

OpenStudy (anonymous):

thank you

OpenStudy (solomonzelman):

good job
