Question

Si: a # b = 2a – b
Determina E = (4 # 3) # (2 # 1)

Answer 1

Respuesta:

7

Explicación paso a paso:

a # b = 2a - b E= (4 #3) # (2 # 1)

4 # 3 = 2(4) - 3 E= 5 # 3

4 # 3 = 8 - 3 E= 7

4 # 3 = 5

a # b = 2a - b

2 # 1 = 2(2) - 1

2 # 1 = 4 - 1

2 # 1 = 3

a # b = 2a - b

5 # 3 = 2(5) - 3

5 # 3 = 10 - 3

5 # 3 =7
