Hello,
First, I just want to say "Hello!" since I am new here. I am just starting my PreCal class this summer. I am a CS major, but have to take it for my degree.
My problem is this:
I have to express the following as a number in the form a/b, assuming a and b are integers.
-2^4 + 3^-1
I know that to get rid of the negative exponent I need to make it 1/3^1. However, I cannot seem to figure it out completely. Any help would be appreciated.
I did it this way and came up with \frac{49}{3}You have this
-2^4+\frac{1}{3}
Now compute 2 to the forth power and then get a common denominator and add.
I know the correct answer is \frac{47}{3} , though.
I have tried to reverse engineer it for a while now, but can't seem to figure out exactly where I am messing it up. I am sure this is a very simple mistake I am making since I did the other questions in the same section without much trouble.
Also, any idea why my fraction tag isn't working?
