Question 396835
{{{log(2, (8xy))}}}
First let's learn how to read or describe this. This expression is "the base 2 logarithm of 8xy".<br>
To write this expression as a sum or difference, we will use a property of logarithms: {{{log(a, (p*q)) = log(a, (p)) + log(a, (q))}}}. This property allows us to write a logarithm of a product as the sum of the logarithms of each factor. Using this property on your logarithms we get:
{{{log(2, (8)) + log(2, (x)) + log(2, (y))}}}
