Thank you for the opportunity to help you with your question!

4+3(8-3)^2

This is how you go about it:


There is an ancient RULE abbreviated BODMAS which gives a guideline on how to work out such problems.

The B stands for BODMAS and tells us that we first work out what is inside the brackets. In our case we  get 8-3 first which gives 5. Rewriting it gives:

4+3(5)^2

Next we Raise the number in the Brackets to the given power, since the orexponent is part of the brackets, we evaluate it before we multiply:

we therefore get  5^2 which gives a 25

Our problem looks like this

4+3(25)

Continue with the brackets again and here we multiply 3 with 25 getting 75 on which we add 4 and our answer becomes .

79




Please let me know if you need any clarification. I'm always happy to answer your questions.

Tutor went the extra mile to help me with this essay. Citations were a bit shaky but I appreciated how well he handled APA styles and how ok he was to change them even though I didnt specify. Got a B+ which is believable and acceptable.
