Please use parentheses! Does "log1/5" mean log(1/5) or log(1))/5? And please show how you got that result.enibaraliu said:

… log A + log B = log ABA logarithm is a mathematical function that represents the number of times a base number must be multiplied by itself to get a given number. It is the inverse of exponentiation.
Logarithms are useful for solving exponential equations and for representing large numbers in a more manageable form. They are also used in many branches of science, such as in chemistry and physics.
To solve a logarithmic equation, you can use the inverse property of logarithms, which states that logb(x) = y is equivalent to by = x. You can also use logarithmic rules, such as the product, quotient, and power rules, to simplify the equation before solving.
The common logarithm is a logarithm with a base of 10. It is commonly denoted as log(x) or log10(x). It is used in many scientific calculations and is the default logarithm on most calculators.
You can check your answers for logarithmic equations by plugging the solution back into the original equation and verifying that it satisfies the equation. You can also use a calculator to evaluate the logarithm and compare it to the original value.
