Identify like terms in the following: (a) \[-x{{y}^{2}},-4y{{x}^{2}},8{{x}^{2}},2x{{y}^{2}},7y,-11{{x}^{2}},-100x,\]\[-11yx,20{{x}^{2}}y,-6{{x}^{2}},y,2xy,3x\]. (b) \[10pq,7p,8q,-{{p}^{2}}{{q}^{2}},-7qp,-100q,-23,\]\[12{{q}^{2}}{{p}^{2}},\] \[-5{{p}^{2}},41,2405p,78qp,13{{p}^{2}}q,\]\[q{{p}^{2}},\] \[701{{p}^{2}}\]

Answer:

                (a) \[-x{{y}^{2}},2x{{y}^{2}};-4y{{x}^{2}},20{{x}^{2}}y;8{{x}^{2}},-11{{x}^{2}},-6{{x}^{2}};\]\[7y,y;-100x,3x;-11yx,2xy\] (b) \[10pq,-7qp,78qp;7p,2405p;8q,-100q;\]\[-23,41;12{{q}^{2}}{{p}^{2}},-{{p}^{2}}{{q}^{2}};-5{{p}^{2}},701{{p}^{2}};13{{p}^{2}}q,q{{p}^{2}}\]
