Vikas TU
On putting x = 1 we get to know that the bi-quad. give zero value and therfore it is the one root for it.
Hence The Products of the roots are=>
for the 4 roots in G.P that is, 1,a,a^2,a^3 is:
a^6 = 27/3 = 9
we get,
a = 3^(1/3) .
Therfore the roots are=>
1,3^(1/3), 3^(2/3) and 3 respectively.
