Learn how to solve problems step by step online. Find the roots of 2log(x)-log(x+6)=0. Apply the formula: a\log_{b}\left(x\right)=\log_{b}\left(x^a\right). The difference of two logarithms of equal base b is equal to the logarithm of the quotient: \log_b(x)-\log_b(y)=\log_b\left(\frac{x}{y}\right). Take the variable outside of the logarithm. Any expression (except 0 and \infty) to the power of 0 is equal to 1.

Final Answer

$x=3$
