Answer 1

если не ошибаюсь там должно быть -349

Answer 2

To evaluate the expression 45 - (19)² - 14 - 19, we need to follow the order of operations, which is commonly known as PEMDAS (Parentheses, Exponents, Multiplication and Division from left to right, Addition and Subtraction from left to right). Let's break it down step by step:

1. Evaluate the exponent: (19)² = 19 * 19 = 361.

Now, the expression becomes: 45 - 361 - 14 - 19.

2. Perform subtraction from left to right:

45 - 361 = -316 (subtracting 361 from 45) -316 - 14 = -330 (subtracting 14 from -316) -330 - 19 = -349 (subtracting 19 from -330)

Therefore, the final result of the expression 45 - (19)² - 14 - 19 is -349.
