Solve without using logarithms
WebSometimes a logarithm is written without a base, like this: log (100) This usually means that the base is really 10. It is called a "common logarithm". Engineers love to use it. On a … WebSolve . First notice that all of the logarithms have the same base. (These are common logarithms, so the bases are all 10.) When using the properties, it is absolutely necessary that the bases are the same. Use the power property to rewrite . 2log 3 as log 3 2. and to rewrite as . log 9 + log 4 – log 3 = log x. Evaluate the exponents.
