-(vi)52pqr(p+q)(q+r)(r+p)-:104pq(q+

Divide as directed.( i 5(2x+1)(3x+5)-:(2x+1) (ii) 26xy(x+5)(y-4)-:13x(y-4)( iii) 52pqr(p+q)(p+r)(r+p)-:104pq(q+r)(r+p)

Divide as directed: 52pqr(p+q)(q+r)(r+p):-104pq(q+r)(r+p)

Divide as directed : 52pqr (p + q) (q + r) (r + p) -: 104pq(q + r) (r + p)

Divide as directed. 52pqr (p+q)(q +r) (r + p) div 104pq(q + r)(r + p)

Using the properties of determinants show that : |[[p^2, q^2, r^2],[qr,rp,pq],[p,q,r]]|=(p-q)(q-r)(r-p)(pq+qr+rp)

If p,q and r are in AP,then prove that (p+2q-r)(2q+r-p)(r+p-q)=4pqr

If q is the mean proportional between p and r , show that : pqr (p + q + r)^(3) = (pq + qr + pr)^(3) .
