Question

Vă rog ! Ex. din poză. Mulțumesc mult !!

Answer 1

1. 5-2+3-1 = 3+2 = 5

2. 2-5+8-2 = -3 + 6 = 3

3. |5-8| - |5-4| - |9-1| + |13-16| = |-3| - |1| - |8| + |-3| = 3-1-8+3 = 2-8+3 = -6 + 3 = -3

Answer 2

Răspuns:

$| - 5| - | + 2| + | - 3| - | - 1| \\ = 5 - 2 + 3 - 1 \\ = 5$

$| - 2| - | - 5| + | + 8| - | - 3 + 5| \\ = 2 - 5 + 8 - 2 \\ = 3$

$|5 - 2 {}^{3} | - |5 - 2 {}^{2} | - |3 {}^{2} - 1| + |13 - 4 {}^{2} | \\ = |5 - 8| - |5 - 4| - |9 - 1| + |13 - 16| \\ = | - 3| - 1 - 8 + 3 \\ = 3 - 1 - 8 + 3 \\ = - 3$
