Answer 1

(351+1 175): (72, 12-40 · 19)​=1526: (72,12 - 760)=1526 : (-687,88) = -2.22

Answer 2

To solve this mathematical expression, you should follow the order of operations (PEMDAS/BODMAS), which stands for Parentheses/Brackets, Exponents/Orders (i.e., powers and square roots, etc.), Multiplication and Division (left-to-right), and Addition and Subtraction (left-to-right).

Let's break down the expression step by step:

1. Start with the operations inside the parentheses: a. Inside the first set of parentheses: 351 + 1 = 352. b. Inside the second set of parentheses: i. 12 - 40 = -28. ii. -28 * 19 = -532.

So, now the expression becomes:

(352) : (-532)

2. Divide 352 by -532:

352 / -532 = -0.66165413534 (approximately, rounded to several decimal places).

So, the result of the expression (351+1 175):(72,12-40·19) is approximately -0.6617.
