If p and q are positive real numbers such that `p^2+""q^2=""1` , then the maximum value of `(p""+""q)` is (1) 2 (2) 1/2 (3) `1/(sqrt(2))` (4) `sqrt(2)`

If p and q are positive real numbers such that p^(2)+q^(2)=1 then find the maximum value of (p+q)

if p and q are positive real numbers such that p^(2)+q^(2)=1 then find the maximum value of (p+q)

If p and q are two quantities such that p^(2) +q^(2) =1 , then maximum value of p + q is

If (p^2)/(q^2) + (q^2)/(p^2) =1, then the value of (p^6 +q^6) is

If p+q=2 , pq=1 then the value of p^3+q^3+6p^2+5q^2+6pq is

For positive real numbers a(a>1) let p_(a) and q_(a), be the maximum values of log_(a)(x) for a<=x<=2a and if p_(a)-q_(a)=(1)/(2) then the value of a is not greater than
