" a."4r'-4p^(3)+4a+1

(3q + 7 p^(2) - 2r^(3) + 4) - (4 p^(2) - 2q + 7r^(3) - 3) = ?

If the coefficients of a^(r-1),a^(r) and a^(r+1) in the binomial expansion of (1+a)^(n) are in A.P. prove that n^(2)-on(4r+1)+4r^(2)-2=0

Let p,q,r varepsilon R^(+) and 27pqr>=(p+q+r)^(3) and 3p+4q+5r=12 then p^(3)+q^(4)+r^(5) is equal to

If p, q and r are perpendicular to q + r, r + p and p + q respectively and if |p + q| = 6, |q + r| = 4sqrt(3) and |r + p| = 4, then |p + q + r| is

Let p , q , r in R^(+) and 27pqr ge (p+q+r)^(3) and 3p+4q+5r=12 . Then the value of 8p+4q-7r=

Let p , q , r in R^(+) and 27pqr ge (p+q+r)^(3) and 3p+4q+5r=12 . Then the value of 8p+4q-7r=
