Question

1,2²:(2 7/13+6/13)-0,3³ = ​

Answer 1

Ответ:

1,2²:(2 7/13+6/13)-0,3³ = ​0.54

Answer 2

Let's break down the expression step by step:

1. First, calculate 2 squared (2²): 2² = 2 * 2 = 4

2. Next, simplify the expression inside the parentheses: (2 7/13 + 6/13)

   To add these fractions, they need a common denominator, which is 13 in this case. So, rewrite 2 as an equivalent fraction with a denominator of 13: 2 = 26/13

   Now, add the fractions: (26/13 + 6/13) = 32/13

3. Now, we have the expression as follows: 4 / (32/13) - 0.3³

4. Divide 4 by (32/13): 4 / (32/13) = 4 * (13/32) = 13/8

5. Finally, calculate 0.3 cubed (0.3³): 0.3³ = 0.3 * 0.3 * 0.3 = 0.027

Now, we have the final expression: (13/8) - 0.027

To subtract these, we need to have a common denominator: (13/8) - (0.027 * 8/8) = (13/8) - (0.216/8)

Now, subtract the fractions: (13/8) - (0.216/8) = (13 - 0.216) / 8 = 12.784 / 8 = 1.598

So, the final result is approximately 1.598.
