Answer:
The value of the expression when b=2 is 21.
Step-by-step explanation:
Consider the provided expression.
[tex] |4b-4|+|3-b^2|+2b^3[/tex]
We need to find the value of expression for b=2.
Substitute the value of b=2 in the provided expression and simplify as shown.
[tex] |4(2)-4|+|3-(2)^2|+2(2)^3[/tex]
[tex] |8-4|+|3-4|+2\times 8[/tex]
Now, the absolute value or modulus of a real number "x" is [tex]|x|=x\ or\ |-x|=x[/tex]
Use the above rule to solve the expression.
[tex] |4|+|-1|+16[/tex]
[tex] 4+1+16[/tex]
[tex]21[/tex]
Hence, the value of the expression when b=2 is 21.
