Question

Evaluate the expression when m = 9
m^2 - 14

Answer 1

Explanation:

`{9}^(2) - 14 = \\ = 81 - 14 = \\ = 67`

Answer 2

• 
  `\Large\boxed{\sf{67}}`

Explanation:

You must find the value of m in order to evaluate the expression.

`\sf{m^2-14}`

For m=9

`\sf{9^2-14}`

Solve.

Use the order of operations.

PEMDAS

• Parentheses
• Exponents
• Multiply
• Divide
• Add
• Subtract

First, do exponents.

`\sf{9^2-14}`

`\sf{9^2=9*9=81}`

`\sf{81-14}`

Subtract.

`\sf{81-14=\boxed{\sf{67}}`

`\Longrightarrow: \boxed{\sf{67}}`

• Therefore, the correct answer is 67.
