An example would be: , is a valid solution, and often this will be all that I'm supposed to give for the answer.

However, in this case (maybe leading up to graphing or word problems) they want me to provide a decimal approximation.

So you could say 10 to this power, and then 10 to this power over here.

If I raise 10 to the power that I need to raise 10 to to get to 3x, well, I'm just going to get 3x.

The next level of this type of log equation may require a calculator to solve.

You'll still find the solution using algebra, but they'll be wanting a decimal approximation for non-"nice" values, which will require "technology".

By the way, when finding approximations with your calculator, don't round as you go along.

Instead, do all the solving and simplification algebraically; then, at the end, do the decimal approximation as one (possibly long) set of commands in the calculator. That's not to say that you can't check your answers for log equation — you most certainly can, and probably should — but you'll need to keep this round-off-error difficulty in mind when checking your solutions.

We also know that if we have a logarithm-- let me write it this way, actually-- if I have b times the log base a of c, this is equal to log base a of c to the bth power.

And we also know, and this is derived really straight from both of these, is that if I have log base a of b minus log base a of c, that this is equal to the log base a of b over c.

The problems in this lesson involve solving logarithmic equations. To learn how to solve logarithmic equations, we start by simply converting the equation from logarithmic to exponential form. For example, when solving logarithmic equations such as 'log base x of 144 equals 2,' we switch from logarithmic to exponential form, to get x^2 = 144, or x = plus or minus 12.…

In this type of log equation, the variable you need to solve for is inside the log, but the equation has more than one log and a constant. You can solve equations with more than one log. To solve log 2 x – 1 + log 2 3 = 5, for instance, first combine the two logs that are adding into one log by using the product rule…

Step 1 Use Known Log Rules. In any problem that involves solving logarithmic equations, the first step is to always try to simplify using the log rules. In this case, we will use the product, quotient, and exponent of log rules. We do this to try to make a polynomial/algebraic equation that is easier to solve.…

Video transcript. The left-hand side is log base 10 of 3x. So if 10 to some power is going to be equal to 3x. And 10 to the same power is going to be equal to 8. So 3x must be equal to 8. 3x is equal to 8, and then we can divide both sides by 3. Divide both sides by 3, you get x is equal to 8 over 3.…
