### Can you change the base of a log?

## Can you change the base of a log?

In order to evaluate logarithms with a base other than 10 or e, we use the change-of-base formula to rewrite the logarithm as the quotient of logarithms of any other base; when using a calculator, we would change them to common or natural logs.

## How do you change log to log?

To convert a number from a natural to a common log, use the equation, ln(x) = log(x) ÷ log(2.71828).

**What is the change of base property?**

Mathwords: Change of Base Formula. A formula that allows you to rewrite a logarithm in terms of logs written with another base. This is especially helpful when using a calculator to evaluate a log to any base other than 10 or e. Assume that x, a, and b are all positive.

**What does change of base formula create?**

### How do you find the base of the same log?

To solve this type of problem:

- Step 1: Change the Base to 10. Using the change of base formula, you have.
- Step 2: Solve for the Numerator and Denominator. Since your calculator is equipped to solve base-10 logarithms explicitly, you can quickly find that log 50 = 1.699 and log 2 = 0.3010.
- Step 3: Divide to Get the Solution.

### Can you multiply logs with different bases?

No. There is a change of base formula for converting between different bases. To find the log base a, where a is presumably some number other than 10 or e, otherwise you would just use the calculator, Take the log of the argument divided by the log of the base.

**How do I change Log10 to log?**

To convert a natural antilog to a base=10 antilog, multiply by the conversion factor 2.303 before taking the natural antilog.. For example, to calculate the base-10 antilog of -8.45: Use your calculator to find InvLn(-8.45*2.303) = InvLn(-19.460).

**How do you convert to natural log?**

If you need to convert between logarithms and natural logs, use the following two equations:

- log10(x) = ln(x) / ln(10)
- ln(x) = log10(x) / log10(e)
