Question

1) 5 - a i 4,8 – a + b;2) 4,5 + m - 9,2 i 7,19 + m;​

Answer 1

Ответ:

1)5 - а і 4,8 - а + b

(5 - a) - (4,8 - a + b) = 5 - a - 4,8 + a - b = 0,2 - b

2)4,5 + m - 9,2 і 7,19 + m

(4,5 + m - 9,2) -(7,19 + m) = 4,5 + m - 9,2 - 7,19 - m = 4,7 - 7,19 = -7,19 - 4,7 = -11,89

Answer 2

To simplify the given expressions, let's perform the operations step by step:

1. 5 - ai + 4.8 - a + b: Combine like terms: (5 + 4.8) - ai - a + b 9.8 - ai - a + b The simplified expression is 9.8 - ai - a + b.

2. 4.5 + m - 9.2i + 7.19 + m: Combine like terms: (4.5 + 7.19) + (m + m) - 9.2i 11.69 + 2m - 9.2i The simplified expression is 11.69 + 2m - 9.2i.

So, the simplified expressions are:

1. 9.8 - ai - a + b
2. 11.69 + 2m - 9.2i
