User blog:Mango523WNR/Vista(0,1)=? No.2

I have tried 5&2.2,but finally failed.

So, I should find a suitable number.

Is it 2.5 or 2.4?

No, I will try 8/3 First.

So, First, (8/3)^^(8/3)

(8/3)^((8/3)^^(5/3))

(8/3)^(8/3)^((8/3)^^(2/3))

Here, We define that a=(8/3)^^(2/3)

So, a=(8/3)^(1/(8/3)^^(1/2))

And, b=(8/3)^^(1/2)

So, b=(8/3)^(3/8)

So, b=1.4445689
