I want to define the function f1(x)= 2^5x, where the power itself is 5x, and not 2^5 multiplied by the power of x.
The calculator keeps assuming that I'm saying f1(x)= (2^5)^x, and thus i can't get it to say that f1(x+y) = 2^5x+y, even though this is the correct answer. It gives me e^ln(32) x (y+x) which is not what im looking for at all.
Damn technology -_-

So you are trying to entercorrect?
Yep, I don't know how to enter maths equations on here sorry!

I just don't know why my calculator insists to give it in that form, since I won't be able to use that in SACs lol (I know it is an easy question that can be done in your head, but i don't trust my calc for harder questions)
Sorry for the confusion. It's contagious.

You could also try pushing the left button after typing 2^5 (presumably after which it takes it back to the level where you're multiplying the 2^5), you should be able to tell by where the cursor is whether or not you're typing it in the "to the power of" section or not.

Just in this case the simplification actually complicates things.

Have you tried entering 2^(5x), typing in the brackets yourself?

It's totally ignoring the brackets, even variations of (2)^5x or 2^(5x). It says that I wrote (2^5)^x = 32^x when i hit enter :( I've even tried to enter the actual answer of 2^(5x+y) (where 5x+y is its own term) and it gives (2^y) x (32^x).
Stevensmay, that's probably the case. Annoying though.
Thanks guys :)
