If `a,b in R` and `a^(*)b=(a)/(a+b)` where `a+b!=0` and `a^(*)b=5` then `b*a=`

If a+b=(1)/(b)+(1)/(a)=(a)/(b),(a+b!=0) where a,b in R-{0},a and b are distinct then

The quadratic equation whose roots are a/b and b/a, a!=b!=0 where a^(2)=5a-3 , and b^(2)=5b-3 , is

Locus of the image of a point A(0,0) in the line (2a+b)x+(3a-2b)y+(b-5a)=0 is (where a and b are parameters).

Let R be a relation defined by R = {(a, b) : a ge b }, where a and b are real numbers, then R is

If (a^(log_b x))^2-5 a^(log_b x)+6=0, where a >0, b >0 & a b!=1, then the value of x can be equal to (a) 2^(log_b a) (b) 3^(log_a b) (c) b^(log_a2) (d) a^(log_b3)
