Question

(-4,16+2,56):3,2-1,2•(-0,6)

Answer 1

(-4,16+2,56):3,2-1,2*(-0,6)= 0,22
1) -4,16+2,56= -1,6
2) -1,6:3,2= -0,5
3) 1,2*(-0,6)= -0,72
4) -0,5+0,72= 0,22

Answer 2

To simplify the expression, let's start by evaluating each part step by step:

1. (-4, 16 + 2, 56): 3,2 This part represents the division of the complex number (-4 + 16i) by the real number 3.2.

   (-4 + 16i) / 3.2 = -1.25 + 5i

2. -1,2 • (-0,6) This part is the multiplication of the real number -1.2 by the real number -0.6.

   -1.2 * (-0.6) = 0.72

Now, let's put the results together:

-1.25 + 5i - 0.72

Finally, simplify the expression:

-1.25 - 0.72 + 5i = -1.97 + 5i

So, the simplified result is -1.97 + 5i.
