WebbTo solve a logarithmic equations use the esxponents rules to isolate logarithmic expressions with the same base. Set the arguments equal to each other, solve the equation and check your answer. What is logarithm equation? A logarithmic equation is an equation that involves the logarithm of an expression containing a varaible. WebbWhen you have logarithms with different bases, it means that you have a logarithmic equation or expression where the bases are of different numbers. The way to go about this is to use a formula called the change of base formula. The aim here is to make the different bases equal. That way, you will be able to get a solution easily. how can a growth mindset help me learnWebbLogarithms are the inverses of exponents.

WebbRemember that a logarithm is the power to which a number must be raised to obtain another number. For example, the base 10 logarithm of 100 is 2, since 10 raised to the power of 2 equals 100: \log (100)=2 log(100) = 2. because: { {10}^2}=100 102 = 100. The base is the number that is being raised to a power. We can use logarithms with any base.
