Question

1. If a * b means a x b + 2 and a #b means - a + b -(-3),
then find the value of the following:
(i) -4*3 (ii) (-3) * (-2) (iii) (-7) # (-3)
(iv) 2 # (-4)​

Answer 1

Step-by-step explanation:

(i)-4*3=>-4×3+2

-12+2=-10

(ii)(-3)*(-2)=>(-3)×(-2)+2

6+2=8

(iii)(-7)#(-3)=>-(-7)+(-3)-(-3)

7-3+3=7

(iv)2#(-4)=>-2+(-4)-(-3)

-2-4+3= -6+3= -3

Answer 2

Answer:

I)-10 II)8 III)7 IV)-3

Step-by-step explanation:

I)-4*3. = (-4×3) + 2 = -12+2= -10.

II)(-3)*(-2) = (-3×-2) +2 = 6+2 = 8.

III)(-7)#(-3) = 7+(-3)-(-3) =7-3+3 = 7.

IV)2#(-4) = -2+(-4)-(-3) = -2-4+3 = -3.
