step 1 :- first of all ,
we see that here
√{(4 - 1/3√2√( 4 -1/3√2).........∞)}
let whole system of this is P
P = √{( 4 -1/3√2√(4-1/3√2)√.....∞) }
here infinte just like same term ,
after first term they are also P { becoz no any effect in infinite term when we do this ,)
so, P = √{(4 -1/3√2)P }
take square both sides
P² = 4 -1/3√2P
3√2P² +P -4.3√2 = 0
3√2P² + P -12√2 = 0
use quadratic formula,
P = { -1 ±√(1 + 288)}/6√2
= { -1 ± 17}/6√2
but P is always positive becoz
P = exponential function .
so, P = (-1 + 17)/6√2 = 8/3√2
now,
= 6 + log{1/3√2×8/3√2 base 3/2 }
= 6 +log{ 4/9 base 3/2 }
= 6 + log { (2/3)^-2 base (3/2) }
= 6 -2
