Question

How do you simplify `[78\div 13] ^ { 2} - 8\cdot 3`?

Answer 1

`12`

Explanation:

Remember PEMDAS(Order of Operations):

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

First, solve anything within the parentheses.
That would be (`78 divide 13`),

`78 divide 13 = 6`

Now we are left with `6^2 -8times3`, the next step is to do do the exponents.

`6^2 = 6times6 = 36`

The equation up to this point would look like: `36 - 8times3`.

Then multiply 8 and 3 together, multiplication comes before subtraction.
`8 times 3` = 24

So we are left with: `36 - 24`
`36 - 24 = 12`
