Answer:
506
Explanation:
According to the order of operations(or PEMDAS), you would first evaluate the exponent in the problem:
.
is equivalent to
, which is just 512. Therefore, the equation would now be 512 - 9 * 2 ÷ 3
Next step would be to do out the multiplication and division left to right. First is 9 * 2 which is 18. Then that is divided by three to get 6. The equation would now be 512 - 6.
512 - 6 is just 506.
