−15+45(15e−10)−10e .

Answer 1

To simplify the expression, we can start by calculating 45(15e−10):

45(15e−10) = 675e - 450

Now we can substitute this result back into the original expression:

-15 + 675e - 450 - 10e

Combining like terms:

(675e - 10e) + (-15 - 450)

= 665e - 465

Therefore, the simplified expression is 665e - 465.
