Answer 2

To calculate the product of two complex numbers, you can use the distributive property and then simplify the result.

Let's calculate (-1.56 - 1.24) multiplied by (-1 5/14):

First, multiply the real parts and the imaginary parts separately:

Real Part: -1.56 * (-1) = 1.56

Imaginary Part: -1.56 * (5/14) = -0.556

Now, multiply the second set of numbers:

Real Part: -1.24 * (-1) = 1.24

Imaginary Part: -1.24 * (5/14) = -0.44285714285714284 (rounded to 6 decimal places)

Now, add the real parts and the imaginary parts together:

Real Part: 1.56 + 1.24 = 2.8

Imaginary Part: -0.556 + (-0.44285714285714284) = -0.9988571428571428 (rounded to 6 decimal places)

So, the product of (-1.56 - 1.24) and (-1 5/14) is approximately:

2.8 - 0.9988571428571428i
