Question

. Evaluate each expression given that X = -2, Y = 8 and Z = 4

1. Z2 + (XY) 2. X2 + Z 3. YZ / X 4. XZ / Y 5. XY / Z a. -4 b. -1 c. -16 d. zero e. 8

Answer 1

hello:-
this(*)is counted as multiplication
1. 4*2 + (-2+8)
=8+(6)
=14
2. (-2)*2 + 4
= -4+4
=0
3. 8*4/-2
= -32/2 (as -ve sign cannot be in denominator)
= -16
4. -2*4/8
= -8/8
= -1
5. -2*8/4
= -16/4
= -4
therefore it is a. -4
I hope it will help u !!!!!!!!!
