Hey guys, another problem.
so when I tried to find the integral of f(x)=8-2^(x-1) and g(x)=(-18/4)x+15/2
I get a decimal. when I try and convert it to exact values it gives me a (51188988/8283293).
but when I do the exact same thing on ti-inspire, I get a 17-(15/2*ln(2)). On the ti-inspire when i change the exact value to a decimal I get the same answer as in the HP Prime.
My question is how can I get my answer to be in the same format as the one on ti-inspire.
Solved! Go to Solution.

yes, I forgot to mention the bound was from 0,4. Which would give you a definite integral replacing the x values
As mentioned in your other recent thread on this forum, if you want exact (symbolic) results, you must use CAS (not Home), lowercase variables (not single-letter uppercase variables). You must also type all numbers without any decimal points, because a decimal point indicates that it's a "floating point" (approximate) value. However, neither integral from 0 to 4 gets the result you mentioned:

Are you sure that you typed them correctly? I copied your formulas and pasted them into WolframAlpha exactly as you typed them, and its results are the same as the HP Prime's results:
