Question

1.If x= -2/3 y=1/4 z= -5/8
verify that
1)x(y+3)=xy+xz
2)y(z-x)=yz-yx​

Answer 1

Answer:

given that x=-2/3,y=1/4,z=-5/8

now taking x(y+3)=-2/3(1/4+3)

=-13/6

now rhs... xy+xz=-2/3)(1/4) +(-2/3)(-5/8)

=-13/6....hence proved

2)..y(z-x)=yz-yx= rhs

hence proved

Answer 2

Answer:

-2/3(1/4+(-5/8)= -2/3(1/4 -5/8)

= -2/3(8-20/32)=-2/3(( by cancellation -2 change into 1 ))

(-12/32) (( by cancellation (-12/32)change into 6/16 and 16 change into 8 it change it into 4 = (-1/6+5/12)

=-12+30/72=18/72(( and by cancellation 18 change into 3 and 72 change into 12 and 3 change into 1 and 12 change into 4.

L.H.S =R.H.S. ,

Hence verified.
