Question

¯\/¯¯0,04 *81 - 7 целых ¯\/¯¯1/49

Answer 1

9*0.2=1.8
1.8-7*1\7=0.8 

Answer 2

To solve this expression, we can start by simplifying each of the terms.

First, let's simplify the square root term:

¯/¯¯1/49 = 1/7

Now let's simplify the first term:

¯/¯¯0,04 *81 = ¯/¯¯(0.04 * 81) = ¯/¯¯3.24 = 1.8

Next, let's subtract 7 from the simplified first term:

1.8 - 7 = -5.2

Putting it all together, we have:

¯/¯¯0,04 *81 - 7 целых ¯/¯¯1/49 = -5.2 - 1/7

Therefore, the final answer is approximately equal to -5.2 - 0.1429, which simplifies to -5.3429.
