OUR TEACHER, AS ALWAYS GAVE US HOMEWORK, WHICH SHE DID NOT EXPLAIN
\(\displaystyle e^{x+2}-1 = 0 \)
Probably the answer is x = -2 but I don't know how to show it mathematically...
NEXT
I've been searching for derivative and found this:
\(\displaystyle \frac{e^3 - e^x}{e^x} < 0 \)
I know that it is not allowed to multiply both sides from denominator in inequalities so I stuck there.. Maybe it's simple but I'd like that you show me how to solve this
