 log_{3 {x}^{2}  + 1}(2)  &lt;  \frac{1}{2}

2 &lt; {(3x {}^{2}  + 1) }^{ \frac{1}{2} }

4 &lt; 3x {}^{2}  + 1

3 &lt; 3 {x}^{2}

 {x}^{2}  &gt; 1

x \: is \: in \: ( -  \infty  \:  - 1) \: u \: (1 \:  \infty )


nitishmadhepura45: since base is variable then it may be >0 and <1 and my be >1.....therefore there should be 2 cases
nitishmadhepura45: anyway, thanks
balakrishna40: base is clearly greater than 1
balakrishna40: so only one case arises
nitishmadhepura45: oo..ya i understood....thanks
balakrishna40: good
nitishmadhepura45: hmm
