Given:
The expression is:
[tex]2b^3+5[/tex]
To find:
The value of the given expression when [tex]b=3[/tex].
Solution:
We have,
[tex]2b^3+5[/tex]
Substituting [tex]b=3[/tex] in the above expression, we get
[tex]2b^3+5=2(3)^3+5[/tex]
[tex]2b^3+5=2(27)+5[/tex]
[tex]2b^3+5=54+5[/tex]
[tex]2b^3+5=59[/tex]
Therefore, the value of given expression at [tex]b=3[/tex] is 59.
