If `p + q = sqrt13 and p -q = sqrt5`, then the value of pq is

If p+q = sqrt(13) and p-q = sqrt(5) , then the value of 2pq is

If p + q = sqrt13 p - q = sqrt5 then the value of pq is ____

If p:q = 5:7 and p-q = -4 , then find the value of 3p+4q.

If p+q = 7 and pq=5, then the value of p^3+q^3 is : यदि p+q = 7 तथा pq = 5 है, तो p^3+q^3 का मान क्या होगा ?

If p:q=5:7 and p-q=-4 then find the value of 3p+4q.

10. If p+q=10 and pq=5, then the numerical value of (p)/(q)+(q)/(p) will be

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