Question

find the value of x if 81x=9÷3x​

Answer 1

$81x = 9 \div 3x \\ \\ = > 81x = \frac{9}{3x} \\ \\ = > 81x \times 3x = 9 \\ \\ = > 243x {}^{2} = 9 \\ \\ = > x {}^{2} = \frac{9}{243} \\ \\ = > x {}^{2} = \frac{3}{81} \\ \\ = > x = \sqrt{ \frac{3}{81} } \\ \\ = > \: x = \frac{ \sqrt{3} }{ \: 9}$
