The difference of two logarithms of equal base $b$ is equal to the logarithm of the quotient: $\log_b(x)-\log_b(y)=\log_b\left(\frac{x}{y}\right)$

$\log_{4}\left(\frac{7}{3x+4}\right)=\log_{4}\left(21\right)$
Learn how to solve problems step by step online. Solve the logarithmic equation log4(7)-log4(3*x+4)=log4(21). 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. Take the reciprocal of both sides of the equation. Apply fraction cross-multiplication.
