<3 Goodluck
Given:
The expression is:
![2b^3+5](https://tex.z-dn.net/?f=2b%5E3%2B5)
To find:
The value of the given expression when
.
Solution:
We have,
![2b^3+5](https://tex.z-dn.net/?f=2b%5E3%2B5)
Substituting
in the above expression, we get
![2b^3+5=2(3)^3+5](https://tex.z-dn.net/?f=2b%5E3%2B5%3D2%283%29%5E3%2B5)
![2b^3+5=2(27)+5](https://tex.z-dn.net/?f=2b%5E3%2B5%3D2%2827%29%2B5)
![2b^3+5=54+5](https://tex.z-dn.net/?f=2b%5E3%2B5%3D54%2B5)
![2b^3+5=59](https://tex.z-dn.net/?f=2b%5E3%2B5%3D59)
Therefore, the value of given expression at
is 59.
