Question

How do you evaluate `(bc^2+a)/c` given a=12, b=9, c=4?

Answer 1

See a solution process below:

Explanation:

Substitute:

• `color(red)(12)` for `color(red)(a)`
• `color(blue)(9)` for `color(blue)(b)`
• `color(green)(4)` for `color(green)(c)` and evaluate the expression:

`(color(blue)(b)color(green)(c)^2 + color(red)(a))/color(green)(c)` becomes:

`((color(blue)(9) xx color(green)(4)^2) + color(red)(12))/color(green)(4) =>`

`((color(blue)(9) xx color(green)(16)) + color(red)(12))/color(green)(4) =>`

`(144 + color(red)(12))/color(green)(4) =>`

`156/color(green)(4) =>`
