Question

1)85,6(20,2-18,51)+13,1362)(11,12+32,68)×17,9-95,02​

Answer 1

Ответ:

85,6•(20,2-18,51)+13,136=85,6*1,69+13,136=144,664+13,136=157.8

 (11,12+32,68)•17,9-95,02=43.8*17,9-95,02=784.02-95,02=689

Answer 2

To solve the given expression, follow the order of operations: parentheses, multiplication and division (from left to right), and finally addition and subtraction (from left to right). Let's break it down step by step:

1. Start with the innermost parentheses: 20.2 - 18.51 = 1.69 11.12 + 32.68 = 43.8

2. Next, perform the multiplication: 13.1362 * 43.8 = 574.02116

3. Now, deal with the outermost parentheses: 85.6 * 1.69 = 144.184 574.02116 + 43.8 = 617.82116

4. Finally, perform the remaining operations (addition and subtraction) from left to right: 617.82116 * 17.9 = 11062.584364

   11062.584364 - 95.02 = 10967.564364

The result of the given expression is approximately 10967.564364.
