Express the numbers in the equation as logarithms of base $10$
$\log \left(x+9\right)=\log \left(10^{1}\right)-\log \left(x\right)$
Learn how to solve problems step by step online. Solve the logarithmic equation log(x+9)=1-log(x). Express the numbers in the equation as logarithms of base 10. Any expression to the power of 1 is equal to that same expression. 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). For two logarithms of the same base to be equal, their arguments must be equal. In other words, if \log(a)=\log(b) then a must equal b.
