How do you multiply logs with the same base?

To multiply logs with the same base, you can use the logarithmic property that states:

logb(x) + logb(y) = logb(xy)

Here’s how it works:

  1. First, ensure that the logarithms you are multiplying share the same base. For example, if you have log10(a) and log10(b), they both have base 10.
  2. According to the property mentioned, you can combine them by adding their logarithmic values together.
  3. So, instead of multiplying log10(a) and log10(b), you can rewrite it as log10(a * b).

For example, if you want to multiply log10(2) and log10(3), you’d rewrite it as:

log10(2) + log10(3) = log10(2 * 3) = log10(6)

This property helps simplify logarithmic expressions and is particularly useful in solving logarithmic equations.
