Any number raised to the power of 1 keeps the same value; any number with an exponent of 0 is equal to 1. Exponentiation is a math operation that raises a number to a power of another number to get a new number. Hide Ads About Ads. On a calculator the Common Logarithm is the "log" button. You William Hill Welcome Bonus have a button for this Romme Spielen Online Kostenlos your calculator as well.In other words:. Because of this special property, the exponential function is very important in mathematics and crops up frequently. Like most functions you are likely to come across, the exponential has an inverse function, which is log e x, often written ln x pronounced 'log x'.

You may often see ln x and log x written, with no base indicated. It is generally recognised that this is shorthand:.

NB: In the above example, I have not written what base each of the logarithms is to. This is because for the laws of logarithms, it doesn"t matter what the base is, as long as all of the logs are to the same base.

If you give "the answer" as being the decimal approximation, you should expect to lose points. I have division inside the log. According to the second of the log rules above, this can be split apart as subtraction outside the log, so:.

The first term on the right-hand side of the above equation can be simplified to an exact value, by applying the basic definition of what a logarithm is.

Always remember to take the time to check to see if any of the terms in your expansion such as the log 4 16 above can be simplified.

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.

Page 1 Page 2 Page 3 Page 4 Page 5. All right reserved. The quantity on the right is the power that the base of 10 has to be raised to in order to equal the argument , or input of the log, the value in parentheses in this case 1, This value has to be positive, because the base — which can be a number other than 10, but is assumed to be 10 when omitted, e.

So how can you work easily between logs and exponents? A few rules about the behavior of logs can get your started on exponent problems.

This leaves you with. Using your calculator or electronic device of choice, you find that the solution is 1. The same rules apply when the base is e , the so-called natural logarithm , which has a value of about 2.

You should have a button for this on your calculator as well. This value gets its own notation, too: log e x is written simply "ln x.

Like most functions you are likely to come across, the exponential has an inverse function, which is log e x, often written ln x pronounced 'log x'.

You may often see ln x and log x written, with no base indicated. It is generally recognised that this is shorthand:. NB: In the above example, I have not written what base each of the logarithms is to.

This is because for the laws of logarithms, it doesn"t matter what the base is, as long as all of the logs are to the same base.

Another important law of logs is as follows. This is a very useful way of changing the base in this formula, the base does matter!

Most calculators can only work out ln x and log 10 x usually just written as "log" on the button so this formula can be very useful. If we are given equations involving exponentials or the natural logarithm, remember that you can take the exponential of both sides of the equation to get rid of the logarithm or take the natural logarithm of both sides to get rid of the exponential.

Notice how we haven"t said what the base is. Many calculators only have "log" and "ln" keys for log to the base 10 and natural log to the base e respectively.

In science, measurements can have a large dynamic range. This means that there can be a huge variation between the smallest and largest value of a parameter.

Now increase the sound level by another factor of 10, i. The magnitude of an earthquake on the Richter scale is determined by using a seismograph to measure the amplitude of ground movement waves.

The log of the ratio of this amplitude to a reference level gives the strength of the earthquake on the scale.

Similar to sound pressure measurements on a log scale, every time the value on the scale increases by 1, this represents a tenfold increase in strength of the earthquake.

So an earthquake of strength 6 on the Richter scale is ten times stronger than a level 5 earthquake and times stronger than a level 4 quake.

Values with a large dynamic range are often represented on graphs with nonlinear, logarithmic scales. The x-axis or y-axis or both can be logarithmic, depending on the nature of data represented.

Each division on the scale normally represents a tenfold increase in value. Typical data displayed on a graph with a logarithmic scale is:. Trip current for an MCB protective device.

These are used to prevent cable overload and overheating when excess current flows. The current scale and time scale are logarithmic.

The frequency scale on the x axis and gain scale on the y axis are logarithmic. Marine Biology. Electrical Engineering. Computer Science.
