Question

please answer it fast it's very urgent​

Answer 1

Answer:

(a2 + 1)/a = 4

a2 + 1= 4a

a2 - 4a + 1=0

by

(-b +-√b2-4ac)/2a

(4+√16-4)/2

(4+2√3)/2

2+√3= a

Similarly

2-√3= a

2(a3+1/a3)

2(a+1/a)(a2 +1/a2 -1)

I have got some work to do...

So sorry..

You can put the value of a in equation and solve..

Remember that there are two values of a...

Sorry again..
