SOLUTION: When solving this problem and using PEMDAS, have I done this correctly?: 36/(-2)^2+4[5-3(8-9)^5] 36/(-2)^2+4[5-3(-1)^5] 36/(-2)^2+4[5-3-1^5] 36/(-2)^2+4[2-1^5] 36/(-2)^2+4[1]

Question 307324: When solving this problem and using PEMDAS, have I done this correctly?:
36/(-2)^2+4[5-3(8-9)^5]
36/(-2)^2+4[5-3(-1)^5]
36/(-2)^2+4[5-3-1^5]
36/(-2)^2+4[2-1^5]
36/(-2)^2+4[1]
36/-4+4*1
-19*4*1
-76*1=-76

Answer by rapaljer(4671) (Show Source): You can put this solution on YOUR website!
36/(-2)^2+4[5-3(8-9)^5]
36/(-2)^2+4[5-3(-1)^5]
36/4+4[5-3*(-1)]
9+4[5+3]
9+4*8
9+32
41

For additional explanation on signed numbers and order of operations, please see my own website. You can find my website by doing a Google search for my name "Dr. Robert J. Rapalje". Look for "Rapalje Homepage", which should be the first item on the search. Once you find my homepage, for a written explanation, click on "Basic, Intermediate, and College Algebra: One Step at a Time." Look in Basic Algebra in Chapter 1 for the appropriate sections. There you will find a detailed explanation, and solutions to problems in LIVING COLOR!!

I have many other topics explained in this way from Basic, Intermediate, and College Algebra. Please check out my website to see what I have. It's all FREE, and if you send me an Email, I'll be glad to help you find something. I'm not selling anything. If you get a good explanation, math is usually not as hard as you think it is.
