Question

5. If p= -8by 27 , q=3by4 and r = -12by15
, then verify that
i) px(qxr)= (pxq)xr
ii) px (q-r)= (pxq)-(pxr)
Name these properties also.​

Answer 1

Answer:

p=8/27

=0.29

q=3/4

=0.75

r=12/15

=0.8

a)p(q*r)=(p*q)r

0.29(0.75*0.8)=(0.29*0.75)0.8

0.29*0.6=0.2175*0.8

0.174=0.174

L.H.S=R.H.S

Similarly the second one
