Question

Please someone tell me how to do the (ii) part of this question. I have an exam in 2 hours.

Answer 1

\[\alpha=\frac{ 3\alpha }{ 4 }+\frac{ 15 }{ \alpha^3 }\]

Answer 2

I can't work out how to find the exact value of alpha.

Answer 3

By solving that equation you posted? Like, that is the equation but you don't know how to solve it?

Answer 4

let x[n]=x[n+1]=a and solve for a

Answer 5

a=3a/4+15/a^3
1=3/4+15/a^4
15/a^4=1/4
a^4=60
a=sqrt(sqrt(60))
