−15+4/5(15e−10)−10e.
To simplify this expression, you'll need to follow the order of operations (PEMDAS/BODMAS).
First, we'll evaluate the exponential term: 15e^-10.
Using a calculator, we find that 15e^-10 ≈ 1.527.
Next, we'll perform the multiplication: 4/5 * 1.527 = 1.2216.
Finally, we simplify the whole expression:
-15 + 1.2216 - 10e.
And that's the simplified expression.
