Question

Si a ✤ b= -a(b) y x ♥ y= x dividido y, calcula el valor de las siguientes expresiones.
a. (8 ✤ 7) + 9
b. (-12 ♥ 4 ) - (5 ✤ 3)
c. (2 ✤ 4)(1 ✤ 5)
d. (-72 ♥ 8) ✤ (16 ♥ 8)
e. (15 ✤ 1) ♥ (3 ✤ -5)

Answer 1

Explicación paso a paso:

a. (8 ✤ 7) + 9

-8(7) +9

= -47

b. (-12 ♥ 4 ) - (5 ✤ 3)

(-12/4)-(-5(3))

(-3)-(-15)

-3+15

= 12

c. (2 ✤ 4)(1 ✤ 5)

((-2)(4))((-1)(5))

(-8)(-5)

= 40

d. (-72 ♥ 8) ✤ (16 ♥ 8)

(-72/8)✤(16/8)

-9✤2

-(-9)(2)

=18

e. (15 ✤ 1) ♥ (3 ✤ -5)

( (-15)(1) )♥((-3)(-5))

-15♥15

-15/15

= -1
