Answer:
5
Step-by-step explanation:
Let's work from the middle of the equation to the outside of it. Our first part of the equation is 3+4, which equals seven, so we have the equation:
81-2[5(7)]
Then, we multiply 5 and 7, which is 35, so we get the equation:
81-2[35]
Then we have -2 outside of the brackets, so we can multiply -2 and 35, which is -75, so we have the equation:
81-75
Which is 5.
