Let's solve the question as a log equation, then we'll have a change of base formula. And actually, we don't even need a calculator to evaluate this top part. Properties of log base 2.

For Log With Base 4, Apply The Product Rule Immediately.

For example, the expression log 3 81 can be written as log 10 81 / log 10 3. For log with base 5, apply the power rule first followed by quotient rule. 81 l l o g 5 3 + 27 l o g 9 36 + 3 4 l o g 7 9.

Examples Of How To Apply The Log Rules.

Logarithms of numbers to the base 10 are named as ‘common logarithm’ and the logarithms of numbers to the base e are called natural or napierian logarithm. Divide both sides by log c a to get y= [log c b]/ [log c a]. Then get the final answer by adding the two values found.
