Question

(0,027:(9/10)2+0,09*10/27)*0,03+0,998= пояснение:девять десятых в квадрате,десять двадцать седьмых

Answer 1

(0,027 : (9/10)^2) + 0,09 * 10/27) * 0,03 + 0,998 = 1

1) (9/10)^2 = 9/10 * 9/10 = 81/100 = 0,81
2) 0,027 : 0,81 = 27/810 = 1/30
3) 0,09 * 10/27 = (0,09*10)/27 = 9/270 = 1/30
4) 1/30 + 1/30 = 2/30 = 1/15
5) 1/15 * 0,03 = 0,03 : 15 = 0,002
6) 0,002 + 0,998 = 1

Answer 2

To solve the given expression, let's break it down step by step:

1. (9/10)2: - First, we calculate 9 divided by 10, which equals 0.9. - Then, we square 0.9, which gives us 0.81.

2. 0.09*10/27: - We multiply 0.09 by 10, resulting in 0.9. - Next, we divide 0.9 by 27, giving us approximately 0.0333.

3. (0.027:0.0333): - We divide 0.027 by 0.0333, which is approximately 0.8108.

4. 0.8108*0.03: - We multiply 0.8108 by 0.03, resulting in approximately 0.0243.

5. 0.0243+0.998: - Finally, we add 0.0243 to 0.998, giving us approximately 1.0223.

Therefore, the value of the given expression is approximately 1.0223.

Please note that the above calculations are based on the given expression and may vary slightly depending on the level of precision used during calculations.
