Let f be a function defined from `F^(+)rarrR^(+).` If `(f(xy))^(2)=x(f – InterviewSolution

1.	Let f be a function defined from `F^(+)rarrR^(+).` If `(f(xy))^(2)=x(f(y))^(2)` for all positive numbers x and y, If `f(2)=6,` find `f(50)`=?A. 20B. 30C. 5D. 40
Answer» Correct Answer - B `(f(xy))^(2)=x(f(y))^(2) and f(2)=6` Put x = 25 and y = 2 `(f(50))^(2)=25(f(2))^(2)=25xx36` `therefore" "f(50)=30`
