Question

I-7,2I-I0,6I+I-3,4I​

Answer 1

Ответ:

10

Пошаговое объяснение:

модуль числа всегда положителен

следовательно

7.2-0.6+3.4=10(перед модулем числа 0.6 стоит знак -)

Answer 2

It looks like you've provided an expression with complex numbers involving "I," which typically represents the imaginary unit. To simplify this expression, let's break it down step by step:

I-7 + 2I - I-10 + 6I + I-3 + 4I

Now, let's group the like terms (terms with "I" and constants) together:

(I + 2I + 6I + 4I) + (-7 - 10 - 3)

Combine the terms with "I":

(1I + 2I + 6I + 4I) + (-7 - 10 - 3)

Now, add the terms with "I" together:

13I + (-7 - 10 - 3)

Next, simplify the constants:

13I - 20

So, the simplified expression is:

13I - 20
