Question

50*(-0,1)^3-25*(-0,1)^2-9

Answer 1

$50*(-0,1)^3-25*(-0,1)^2-9=-0,05-0,25-9=-9,3$

Answer 2

To evaluate the expression, let's simplify it step by step:

1. First, let's calculate (-0.1)^3: (-0.1)^3 = -0.1 * -0.1 * -0.1 = -0.001

2. Next, let's calculate (-0.1)^2: (-0.1)^2 = -0.1 * -0.1 = 0.01

Now, we can substitute these values back into the expression:

50 * (-0.001) - 25 * 0.01 - 9

Performing the calculations:

= -0.05 - 0.25 - 9

= -0.3 - 9

= -9.3

Therefore, 50 * (-0.1)^3 - 25 * (-0.1)^2 - 9 equals -9.3.
