Learn about logarithms, which are the inverses of exponents use logarithms to solve various equations then analyze both logarithmic and exponential functions and their graphs. This video looks at converting between logarithms and exponents, as well as, figuring out some logarithms mentally it includes 8 examples. The logarithmic functions log b x and the exponential functions b x are inverse of each other, hence y = log b x is equivalent to x = b y where b is the common base of the exponential and the logarithm the above equivalence helps in solving logarithmic and exponential functions and needs a deep understanding examples, of how the above relationship between the logarithm and exponential may be.
Logarithms don’t know about how long a change took (we didn’t plug in 10 years, right) they give us a rate as if all the change happened in a single time period the change could indeed be a single year of 374% continuous growth, or 2 years of 187% growth, or some other combination. To synopsize, these are the things you should know from this lesson so far: the relationship: log b (x) = y means the same thing as b y = xlogarithms are really exponents (powers) they're just written differently.
Solving exponential equations [fbt] (step-by-step) - duration: 29:19 fort bend tutoring 204,528 views 29:19 properties of logarithms - everything you need to know . When rewriting an exponential equation in log form or a log equation in exponential form, it is helpful to remember that the base of the logarithm is the same as the base of the exponent check your understanding.
Explains how logarithms relate to exponentials, stressing 'the relationship' between the two shows how to convert between logarithmic and exponential forms. Exponents, roots, and logarithms here is a list of all of the skills that cover exponents, roots, and logarithms these skills are organized by grade, and you can move your mouse over any skill name to preview the skill. Logarithms are the opposite of exponentials, just as subtraction is the opposite of addition and division is the opposite of multiplicationlogs undo exponentials technically speaking, logs are the inverses of exponentials in practical terms, i have found it useful to think of logs in terms of the relationship.

Here’s a trick for thinking through problems involving exponents and logs just ask two questions: 1) are we talking about inputs (cause of the change) or outputs (the actual change that happened.
