evaluate the expression for the given value of the variable
\[\left| -4b-8 \right|+\left| \left| -1-b ^{2} \right| \right|+2b ^{3} \]
b=-2
\(\large\color{black}{ \displaystyle \left| -4b-8 \right|+\left| -1-b ^{2} \right|+2b ^{3} }\) you mean like this?
without dobule bars.
double* bars
yes
Then plug in -2 for b. \(\large\color{black}{ \displaystyle \left| -4(-2)-8 \right|+\left| -1-(-2) ^{2} \right|+2(-2) ^{3} }\)
my final answer is 13
I think that is incorrect.
\(\large\color{black}{ \displaystyle \left| -4(-2)-8 \right|+\left| -1-(-2) ^{2} \right|+2(-2) ^{3} }\) \(\large\color{black}{ \displaystyle \left| 8-8 \right|+\left| -1-(-2) ^{2} \right|+2(-2) ^{3} }\) \(\large\color{black}{ \displaystyle \left| 0 \right|+\left| -1-(-2) ^{2} \right|+2(-2) ^{3} }\) \(\large\color{black}{ \displaystyle \left| -1-(-2) ^{2} \right|+2(-2) ^{3} }\)
\(\large\color{black}{ \displaystyle \left| -1-(-2) ^{2} \right|+2(-2) ^{3} }\) \(\large\color{black}{ \displaystyle \left| -1-4 \right|+2(-2) ^{3} }\) \(\large\color{black}{ \displaystyle \left| -5 \right|+2(-2) ^{3} }\) \(\large\color{black}{ \displaystyle 5+2(-2) ^{3} }\) \(\large\color{black}{ \displaystyle 5+2(-8) }\)
and on...
and you then get a negative number, that I will give you.
@SolomonZelman would you add 5 and 2 and then multiply 7 by -8
@SolomonZelman and the answer would be -56?
You first multiply.
So it is `(-2)•8` And only then, you add 5
-11?
Yes
thank you
good job
