−15+45(15e−10)−10e .(1 p

To solve this expression, we need to follow the order of operations, which is parentheses, exponents, multiplication/division (from left to right), and finally addition/subtraction (from left to right).

The expression is: −15+45(15e−10)−10e

First, we evaluate the expression inside the parentheses.
15e - 10 = (15)(e) - 10

Next, we multiply 45 by (15e - 10) and substitute the value of (15)(e) - 10.
45(15e - 10) = 45(15)(e) - 45(10)

Now, we substitute the value of 45(15)(e) - 45(10) into the original expression.
-15 + 45(15e - 10) - 10e = -15 + (45(15)(e) - 45(10)) - 10e

Next, we simplify the expression inside the parentheses.
-15 + (45(15)(e) - 45(10)) - 10e = -15 + (675e - 450) - 10e

Next, we simplify further by combining like terms.
-15 + (675e - 450) - 10e = -15 + 675e - 450 - 10e = (675e - 10e) - 15 - 450

Finally, we combine like terms to get the final answer.
(675e - 10e) - 15 - 450 = 665e - 465

Therefore, the simplified expression is 665e - 465.
