Ответ: 0,5

Answer 3

To simplify the expression |0,9| - |-2/5| with square brackets, we first need to evaluate the absolute values and then perform the subtraction.

Step 1: Evaluate the absolute values |0.9| = 0.9 (since 0.9 is positive) |-2/5| = 2/5 (since the absolute value of any number is always positive)

Step 2: Perform the subtraction 0.9 - 2/5 = (4.5/5) - (2/5) = (4.5 - 2)/5 = 2.5/5 = 1/2

So, the simplified expression with square brackets is:

[|0,9| - |-2/5|] = [1/2]
