Learn how to solve logarithmic equations problems step by step online. Solve the logarithmic equation log4(8)-log4(x)=16. 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). Rewrite the number 16 as a logarithm of base 4. 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.

Final answer to the problem

$x=\frac{8}{4^{16}}$
