When adding two logarithms together you simply multiply the vaule
you’re trying to find the answer to, and then take the logarithm
of that number.
log3 + log9 = log 27
log17 + log2 =log34
When subtracting two logarithms you need to divide them. Find the
logarithm of the two numbers you’re trying to find the answer
to by dividing the first number by the second number, and then take
the logarithm of that.
log(3) - log(9) = log(3/9)
log(17) - log(2) = log(17/2)
When trying to find the logarithm of a value that’s raised
to an exponent, then you drop the exponent to the beginning of the
equation, and then multiply the logarithm of the value, by the exponent.
When the base number, and the value you’re trying to find
the function of are the same number, then the answer is always going
to be 1.
