Question

((1,7)во 2 степени -2,2):0,3

Answer 1

((1,7)² - 2,2) : 0,3 = 2,3

1) (1,7)² = 1,7 · 1,7 = 2,89

2) 2,89 - 2,2 = 0,69

3) 0,69 : 0,3 = 2,3

Ответ: 2,3.

Answer 2

Let's break down the expression step by step:

1. (1, 7) во 2 степени - 2 This part appears to be written in Russian and translates to "(1, 7) to the power of 2 - 2". Therefore, we need to calculate (1, 7) squared and then subtract 2 from the result:

(1, 7) во 2 степени = 1^2, 7^2 = 1, 49 (1, 7) во 2 степени - 2 = 1, 49 - 2 = -1, 47

2. -1, 47 : 0, 3 Now, we need to divide -1.47 by 0.3:

-1.47 ÷ 0.3 ≈ -4.9

So, the final result of the expression is approximately -4.9.
