If `3^x=4^(x-1)` , then `x=` `(2(log)_3 2)/(2(log)_3 2-1)` (b) `2/(2-(log)_2 3)` `1/(1-(log)_4 3)` (d) `(2(log)_2 3)/(2(log)_2 3-1)`

Explanation

1)`log_2^7` this term is positive

2)`log_0.2^3` this term is negative

3)`log_(1/3)^(1/5)` this term is positive

4)`log_4^3` this term is positive

5)`log_2^(log_2^9)` this term is positive.
