Answer 2

Given:

The expression is:

`2b^3+5`

To find:

The value of the given expression when
`b=3`.

Solution:

We have,

`2b^3+5`

Substituting
`b=3` in the above expression, we get

`2b^3+5=2(3)^3+5`

`2b^3+5=2(27)+5`

`2b^3+5=54+5`

`2b^3+5=59`

Therefore, the value of given expression at
`b=3` is 59.
