Question

log4x+log4(x-12)=3 solve


​

Answer 1

Step-by-step explanation:

$log(4x) + log(4(x - 12)) = 3 \\ log(4x) + log(4x ) - log(48 ) \\ log(16 {x}^{2} ) - log(48) = 3 \\ log( {16x}^{2} ) \div 48 = 3 \\ log( {x}^{2} ) \div 3 = 3 \\ removing \: log \\ {x}^{2} \div 3 = {10}^{3 } \\ x = \sqrt{1000 \div 3 } \\ = 10( \sqrt{10 \div 3)}$
