What is the purpose of the change of base formula? Why is it useful when using a calculator? Choose ALL correct answers. The formula allows us to rewrite a logarithm that is in terms of common or natural logs as a logarithm in other bases so a calculator can be used to evaluate it Most calculators have the capability of evaluating only common and natural logarithms There is no good purpose for this formula The formula allows us to rewrite a logarithm in terms of logs written with another base

The change of base formula is a lifesaver when it comes to using calculators! Most calculators are equipped to handle just common (base 10) and natural (base e) logarithms, so when you're faced with a different base—like log base 2 or any other—it can feel like a hassle. The formula allows you to convert those tricky logarithms into forms that your trusty calculator can handle, giving you accurate results in a flash. Imagine you're trying to solve a complex equation involving logarithms, but your calculator is stubbornly refusing to cooperate with your chosen base. By using the change of base formula, you can transform that pesky log into a form that allows you to easily calculate it using the logarithmic functions available on your device. This makes you feel like a math wizard, turning frustrations into triumphs—all while ensuring your calculations stay accurate and within reach!
