How do you simplify 3^3- 8 times 3 ÷ 12 using order of operations?

1 Answer

25

Explanation:

According to PEMDAS, (do I even need to say this?) exponents should go first.

color(red)(3^3)-8times3div12

In my own words, exponents are numbers which shows how many times the main number must multiply by itself like this: 3times3xx3

So, 3 times 3 is 9, 9 times 3 is 27.

color(red)(27)-8xx3div12

We should multiply after that, so it will be:

27-color(red)(8times3)div12

27-color(red)(24)div12

Division is next now,

27-color(red)(24div12)

27-color(red)(2)

Now subtract.

color(red)(27-2)

And you get 25.

Hope this helped!
