Question

log (log3(x2 - 1)) = 0
​

Answer 1

log(log3(x-1)(x+1))

log(log3(x-1)+log3(x+1))

2xlog(log3)

Answer 2

$log( log3( {x}^{2} - 1 ) ) = 0 \\ \\ = > log( log3( {x}^{2} - 1 ) ) = log1 \\ \\ = > log3( {x}^{2} - 1 ) = 1 \\ \\ = >0.47712( {x}^{2} - 1) = 1 \\ \\ = > {x}^{2} - 1 = 1 - 0.47712 \\ \\ = > {x}^{2} - 1 = 0.52288 \\ \\ = > {x}^{2} = 1.52288 \\ \\ = > x = 1.234$
