Use the correct order of operation to solve the following problem 3x (50 - 6^2) ÷ 2 =
Effectus [21]

Answer: 21

Step-by-step explanation:

Ok so first of all the numbers in the parentheses go first.

So 6 to the power of 2 (6^2) would be 6x6 which equals 36

50-36=14

After that you just keep rewriting the problem after every step.

Since the 3 is outside of the parentheses, you would multiply it with the 14

3x14=42

Finally 42÷ 2=21

3x (50 - 6^2) ÷ 2 =

        3(14)÷ 2

           42÷ 2= <u><em>21</em></u>

<u><em></em></u>

<u><em></em></u>

<u><em>Hope this helps (:</em></u>

<u><em>Btw sorry if it's a bit confusing but the answer is 21</em></u>
