Question

Compute 5e^2 - 4g + 7 where e = 4 and g = 6 ? (Not sure how to type a squared number where e^2 = “e squared”)

Answer 1

63

Explanation:

The given expresion is

`5 {e}^(2) - 4g + 7`

We want to find the value of this expression when e=4 and g=6.

We substitute these values to get:

`5( {4}^(2) ) - 4(6) + 7`

We evaluate to obtain:

`5(16) - 4(6) + 7`

Let us multiply out to get:

`80 - 24 + 7`

This simplifies to 63
