**The Math Blog Addition of Logarithms**

We can change any base to a different base any time we want. The most used bases are obviously base 10 and base e because they are the only bases that appear on your calculator!! Change of base formula Log b x = Log a x/Log a b Pick a new base and the formula says it is equal to the log of the number in the new base divided by the log of the old base in the new base. Examples 1) Log 2 37... Now that we have looked at a couple of examples of solving exponential equations with different bases, letâ€™s list the steps for solving exponential equations that have different bases. The direct ions say, â€œ Take the common logarithm or natural logarithm of each side.

So if we add 3 to both sides, we are going to get, log base 10 of 7 + 3, plus 3. And this +3 is of course outside of the logarithm to make it clear, it's just like that. And on the right hand side this is going to be equal to, this is going to be equal to just 2T. And now to solve for T we just divide both sides by 2. So if we divide both sides by 2 we get, T is equal to all of this business... The logBASE( command in this case saves one byte, so it is a minor optimization. However, for compatibility across calculators it would be better to use the traditional method in programs as it is only a byte more yet can be used by calculators that do not have the 2.53 MP OS.

**Solving Exponential Equations with Different Bases**

These laws only apply to expressions with the same base, for example, 3 4 and 3 2 can be manipulated using the Law of Indices, but we cannot use the Law of Indices to manipulate the expressions 3 5 and 5 7 as their base differs (their bases are 3 and 5, respectively).... log (ab 2) + log (a 2 b) = log (a 3 b 3) Note that in the above examples, the bases of each logarithm are assumed to be same. In case of logarithms with different bases, first convert their bases to the same base, and then simplify the logarithms.

**VB Helper HowTo Calculate logarithms in different bases**

To Ishelton- I think you are just messing up on your order of operations when entering it into the calculator. What I assume you meant was 10^(8.89932-10), but instead the calculator sees it as (10^8.993) - 10. If you want to calculate a different base other than ten, then just use your log rules... The examples above are very simple uses of the log rules, as applied to the expansion of log expressions. On the next page, we'll take a look at the sort of exercises you'll be seeing in your homework and on the next test.

## How To Add Logs With Different Bases

### log1 = 0, log m m = 1 The logarithm of 1 to any base is always 0, and the logarithm of a number to the same base is always 1. In particular, log 10 10 = 1, and log

- To solve exponential problems with different bases we t ake the common logarithm or natural logarithm of each side. Use the properties of logarithms to rewrite the problem.

- Your two logarithms have difference bases, 9 and 3, and different arguments, and x. So we cannot add them, So we cannot add them, Another way to combine two logarithms into one is to use a property of logarithms.
- I want to have the x-axis logarithmic to the base 2: From 2^10 to 2^25 and at each step the exponent should increase by one, while the y-axis should be linear.
