Simplify using the properties of logarithms: \log_{9}x^{2}

x\log_{9}2

\log_{9}2x

\log_{9}4x

2\log_{9}x

When using the power rule, the coefficient of the logarithm applies to everything in the argument of the logarithm, not just the variable.

For example, 4\log10ab = \log(10ab)^{4} = \log10^{4}a^{4}b^{4} = \log10,000a^{4}b^{4}

Why can't this expression be combined? \log_{2}5-\log_{5}2

The bases are not the same

The arguments are not the same

5 is not divisible by 2

2 is not divisible by 5
