Question

How do you evaluate `12+ 4^ { 2} \times 3- 9`?

Answer 1

12 + (4*4) * 3 - 9 ---> 12 + 16 * 3 - 9 ---> 12 + 48 - 9 ---> 60 - 9 ---> 51

Answer 2

51

Explanation:

You need to apply PEMDAS, the order of operations:

1. Parentheses
2. Exponents
3. Multiplication or Division
4. Addition or Subtraction

See below...

`12 + 4^2 * 3 - 9`
`12 + 16 * 3 - 9` (You do the exponents)
`12 + 48 - 9` (You do the multplication)
`60 - 9` (You do the addition)
`51` (You do the subtraction)

So 51 is the answer.
