Question

Completa con el número que corresponda en cada caso. (“∧” simboliza y , lal simboliza valor absoluto de a, es decir se tomaban los valores positivo y negativo)

1) a . b = 20 ∧ a = - 5 ⥤ b =

2) lal = 7 ∧ a < 0 ⥤ a =

3) a - b = 7 ∧ a = 2 ⥤ b =

4) a : b = 1 ∧ a = - 6 ⥤ b =

5) a . b = 0 ∧ a = - 5 ⥤ b =

6) a² = 25 ∧ a < 0 ⥤ a =

7) a + b = 12 ∧ a = 20 ⥤ b =
​

Answer 1

Respuesta:

1) a . b = 20 ∧ a = - 5 ⥤ b = -4

2) lal = 7 ∧ a < 0 ⥤ a = -7

3) a - b = 7 ∧ a = 2 ⥤ b = -5

4) a : b = 1 ∧ a = - 6 ⥤ b = -6

5) a . b = 0 ∧ a = - 5 ⥤ b = 0

6) a² = 25 ∧ a < 0 ⥤ a = -5

7) a + b = 12 ∧ a = 20 ⥤ b = -8

Explicación paso a paso:

1) a . b = 20 ∧ a = - 5 ⥤ b = -4

2) lal = 7 ∧ a < 0 ⥤ a = -7

3) a - b = 7 ∧ a = 2 ⥤ b = -5

4) a : b = 1 ∧ a = - 6 ⥤ b = -6

5) a . b = 0 ∧ a = - 5 ⥤ b = 0

6) a² = 25 ∧ a < 0 ⥤ a = -5

7) a + b = 12 ∧ a = 20 ⥤ b = -8
