$\log_{x}\left(4\right)=2$
Learn how to solve equations logarithmiques problems step by step online. logx(100)-logx(25)=2. Apply the formula: \log_{b}\left(x\right)-\log_{b}\left(y\right)=\log_{b}\left(\frac{x}{y}\right), where b=x, x=100 and y=25. Apply the formula: \log_{a}\left(x\right)=\frac{\log_{x}\left(x\right)}{\log_{x}\left(a\right)}, where a=x and x=4. Apply the formula: \log_{b}\left(b\right)=1, where b=4. Apply the formula: \frac{a}{x}=b\to \frac{x}{a}=\frac{1}{b}, where a=1, b=2 and x=\log_{4}\left(x\right).
