" (iv) "quad 3p^(2)q^(2)+2p^(3)q+9pq^(2)

Given that p = -3 and q = 2, evaluate p^(2)+(-pq^(2))-p^(2)q^(2) .

If p = -2, q = - 1 and r = 3, find the value of (i) p^(2) + q^(2) - r^(2) (ii) 2p^(2) - q^(2) + 3r^(2) (iii) p - q - r (iv) p^(3) + q^(3) + r^(3) + 3 pqr (v) 3p^(2) q + 5pq^(2) + 2 pqr (vi) p^(4) + q^(4) - r^(4)

If two positive integers a and b are expressible in the form a=pq^(2) and b=p^(3)q;p,q being prime numbers,then LCM(a,b) is pq( b) p^(3)q^(3) (c) p^(3)q^(2)( d )p^(2)q^(2)
