Note: Use 2.71 for e and 3.14 for pi.

A. (e + pi)/(e - pi)

B. e^2 • pi^2

C. e^(pi) + pi^(e)

D. pi^(e) - e^(pi)

Use 2.71 for e and 3.14 for pi.

A.
(e + pi)/(e - pi)
=(2.71 +3.14)/(2.71 -3.14)
=(5.85)/(-0.43)
=-13.605

B.
e^2 • pi^2
=2.71^2 • 3.14^2
=72.401

C.
e^(pi) + pi^(e)
=2.71^(3.14) + 3.14^(2.71)
=22.883559193263366+ 22.21668954600232
=45.1

D.
3.14^(2.71) - 2.71^(3.14)
=22.21668954600232- 22.883559193263366
=-0.67

Exactly what I thought.

You understand that these are basic arithmetic, don't you?
A. (2.71+ 3.14)/(3.14- 2.71)
B. (2.71)^2(3.14)^2
C. (2.71)^{3.14}+ (3.14)^{2.71}
D. (3.14)^{2.71}- (2.71)^{3.14}

And you are told to use a calculator. Do you not know how to do these on a calculator?

I understand this is basic stuff. I post questions in terms of all levels of math. It is my contribution to the site.

These are NOT "contributions"! You are asking for someone else to do your work for you.

Brother, look at most of my threads. I joined this site to get away from arguments and confrontations. My questions are very specific. When I seek hints, I say so. When I seek the full solution, I say so. Most of threads, not all, but most of my threads show effort on my part.
