Answer 1

7,2-3,4+5,8=9,6
Любое отрицательное число под модулем превращается в положительное

Answer 2

To calculate the expression |-7,2| - |3,4| + |-5,8|, we need to find the absolute values of the given numbers and perform the arithmetic operations.

The absolute value of a complex number (a, b) is given by √(a^2 + b^2).

First, let's find the absolute values of the given complex numbers: |-7,2| = √((-7)^2 + 2^2) = √(49 + 4) = √53 |3,4| = √(3^2 + 4^2) = √(9 + 16) = √25 = 5 |-5,8| = √((-5)^2 + 8^2) = √(25 + 64) = √89

Now, substitute these values back into the expression: √53 - 5 + √89

The expression cannot be simplified further unless we have the exact values of √53 and √89.
