Question

Di berikan P={1,2,4,8} , Q={3,4,5,7} dan R={1,2,3,6,9} tentukanlah a) (PUQ)-(QUR)
b) P-Q
c) (PnQ)-R
d) Pn(Q-R)
e) (PUR)-(PnR)
tolong pake cara ya frens...Trimss

Answer 1

A. PUQ= {1,2,3,4,5,7,8}
QUR= {1,2,3,4,5,6,7,9}
PUQ -QUR = {6,9}
b. P - Q = {1,2,8}
c. PnQ = {4}
PnQ - R = {4}
d. Q - R = {4,5,7}
Pn(Q-R)= {1,2,4,5,7,8}
e. PUR = {1,2,3,4,6,8,9}
PnR = {1,2}
(PUR)-(PnR)= {3,4,6,8,9}
