Answer 1

Ответ:

-51,7

Пошаговое объяснение:

-15,4-(-34,26)-24,19-(-4,52)+(-81,69)=-15,4+34,26-24,19+4,52-81,69=-51,7

Answer 2

Ответ:

82,5

Пошаговое объяснение:

-15,4-(-34,26)-24,19-(-4,52)+(-81,69)=82,5

1) -15,4-(-34,26)=-15,4+34,26=+(34,26-15,40)=18,86

2)18,86-24,19=-(24,19-18,86)=-5,33

3)-5,33-(-4,52)=-5,33+4,52=-(5,33-4,52)=-0,81

4)-0,81+(-81,69)=-(0,81+81,69)=82,5

Answer 3

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

-15,4 - (-34,26) - 24,19 - (-4,52) + (-81,69)

First, let's simplify the double negation:

-15,4 + 34,26 - 24,19 - (-4,52) + (-81,69)

Next, let's simplify the subtraction of negative numbers:

-15,4 + 34,26 - 24,19 + 4,52 + (-81,69)

Now, let's add the real parts and the imaginary parts separately:

Real parts: -15 + 34 - 24 + 4 - 81 = -82 Imaginary parts: 4 + 26 - 19 + 52 + 69 = 132

Finally, combining the real and imaginary parts, we get:

-82 + 132i

Therefore, the result of the expression -15,4 - (-34,26) - 24,19 - (-4,52) + (-81,69) is -82 + 132i.
