Question

(-5,17-(-6,97))÷(-3,6)=​

Answer 1

Ответ:0 : (2 12/17 + 1 5/17) - (3 4/5 + 1 3/5) : 6 = 1,6

Пошаговое объяснение:

1) 2 12/17 + 1 5/17 = 3 17/17 = 4

2) 10 : 4 = 2,5

3) 3 4/5 + 1 3/5 = 4 7/5 = 5 2/5 = 5,4

4) 5,4 : 6 = 0,9

5) 2,5 - 0,9 = 1,6

Answer 2

To calculate the expression (-5,17 - (-6,97)) ÷ (-3,6), you can follow these steps:

1. Subtract the second complex number from the first complex number: (-5,17) - (-6,97) = (-5,17) + (6,97) = (1, -80).

2. Now, divide the result by the third complex number: (1, -80) ÷ (-3,6).

To divide complex numbers, you can use the formula:

(a, b) ÷ (c, d) = ((a * c + b * d) / (c^2 + d^2), (b * c - a * d) / (c^2 + d^2))

In this case:

(a, b) = (1, -80) (c, d) = (-3, 6)

Now, plug these values into the formula:

((1 * -3 + (-80) * 6) / (-3^2 + 6^2), ((-80) * (-3) - 1 * 6) / (-3^2 + 6^2))

Simplify:

((-3 - 480) / (9 + 36), (240 + 6) / (9 + 36))

((-483) / 45, 246 / 45)

Now, divide both the real and imaginary parts by 45:

Real part: (-483) / 45 = -10.7333 (rounded to 4 decimal places) Imaginary part: 246 / 45 = 5.4667 (rounded to 4 decimal places)

So, the result is approximately (-10.7333, 5.4667).
