Answer 2

To evaluate the expression 2,1:а + 17 and 2/5 * 0,8 when а = 36, we can substitute the value of а into the expression and perform the calculations.

Let's start with the first expression: 2,1:а + 17.

Substituting а = 36, we have:

2,1:36 + 17

To calculate 2,1:36, we divide 36 by 2.1:

2,1:36 = 36 / 2.1

Evaluating this division:

2,1:36 ≈ 17.142857142857142

Now we can add 17 to this result:

17.142857142857142 + 17 ≈ 34.142857142857142

So, when а = 36, the value of the expression 2,1:а + 17 is approximately 34.142857142857142.

Moving on to the second expression: 2/5 * 0,8.

Substituting the values:

2/5 * 0.8

Evaluating this multiplication:

2/5 * 0.8 = 0.32

So, when а = 36, the value of the expression 2/5 * 0.8 is 0.32.
