If `a/b=c/d=e/f,` then show that `(a^(3)b+2c^(2)e-3ae^(2)f)/(b^(4)+2d^(2)f-3bf^(3))=(ace)/(bdf)`(wherever defined)

If (a)/(b)=(c)/(d)=(e)/(f) , then (a^(3)+c^(3)+e^(3))/(b^(3)+d^(3)+f^(3))=_____

If (a)/(b)=(c)/(d)=(e)/(f)=3 , then (2a^2 + 3c^(2) + 4e^(2))/(2b^(2) + 3d^(2) + 4f^(2))=?

If (a)/(b)=(c)/(d)=(e)/(f) and (2a^(4)b^(2)+3a^(2)c^(2)-5e^(4)f)/(2b^(6)+3b^(2)d^(2)-5f^(5))=((a)/(b))^(n) then find the value of n.

If a/b=c/d=e/f=3/4 , then (a+c-e)/(b+d-f) is:

If a/b = c/d = e/f , then prove that each of these ratio's is equal to ((4a^(2)+3c^(2)-7e^(2))/(4b^(2)+3d^(2)-7f^(2)))^(1//2)
