## Homework Statement

why is the answer not e^10x ?

If you ignore the e's it should be

5x - 5x + 5x - - 5x, or

5x - 5x + 5x + 5x, which is 10x

If you ignored the e's, it wouldn't be a hyperbolic function, but a linear function.

[tex]

e^{x} + e^{y} \neq e^{x + y}

[/tex]

For example: Take [itex]x = y = 0[/itex] and compare the two sides of this

But your comment indicates a deeper confusion about exponents and algebraic principles. I would suggest that it might be a good idea to review basic algebra including the rules of exponentiation.
