-15+4/5 (15e-10)-10e

Answer 1

To simplify the expression, we can follow the order of operations (PEMDAS).

First, we can simplify the denominator of the fraction:
4/5 = 0.8

The expression now becomes:
-15 + 0.8(15e-10) - 10e

Next, we can simplify the multiplication:
0.8(15e-10) = 12e-10

The expression now becomes:
-15 + 12e-10 - 10e

Finally, we combine like terms by adding/subtracting the coefficients of the same variable (e):
-15 - 10e + 12e-10
