Question

Evaluate f + g2 - 3g if f= 3 and g = 5.

Answer 1

`\boxed{ \bold{ \huge{ \boxed{ \sf{13}}}}}`

Explanation:

Given, f = 3 and g = 5

`\sf{f + {g}^(2) - 3g}`

Plug the values

⇒
`\sf{3 + {5}^(2) - 3 * 5}`

Evaluate the power

⇒
`\sf{3 + 25 - 3 * 5}`

Multiply the numbers : 3 and 5

⇒
`\sf{3 + 25 - 15}`

Add the numbers : 3 and 25

⇒
`\sf{28 - 15}`

Subtract 15 from 28

⇒
`\sf{13}`
