Convert from logarithmic to exponential form. In order to analyze the magnitude of earthquakes or compare the magnitudes of two different earthquakes, we need to be able to convert between logarithmic and exponential form. For example, suppose the amount of energy released from one earthquake were 500 times greater than the amount of energy ...
where, we read [latex]{\mathrm{log}}_{b}\left(x\right)[/latex] as, “the logarithm with base b of x” or the “log base b of x.”; the logarithm y is the exponent to which b must be raised to get x.; Also, since the logarithmic and exponential functions switch the x and y values, the domain and range of the exponential function are interchanged for the logarithmic function.
To write an equation in logarithmic form, remember the pattern logb(a) = c, where b is the base, a is the result, and c is the exponent. For example, the equation 3^2 = 9 can be rewritten in logarithmic form as log3(9) = 2. Writing Equations in Exponential Form. To convert a logarithmic equation into exponential form, remember the pattern b^c = a.
Convert the following to exponential form : log √3 9 = 4. Solution : 9 = (√3) 4. Example 4 : Convert the following to exponential form : log 10 0.1 = -1. Solution : 0.1 = 10-1. Example 5 : Convert the following to exponential form : log 0.5 8 = -3. Solution : 8 = 0.5-3. Example 6 : Convert the following to logarithmic form : 1/1296 = 6-4
Rewriting a natural logarithm in exponential form can make solving easier. This tutorial shows you how to take a natural logarithm and convert it to exponential form! Keywords: problem; convert; change; form; natural logarithm; log; exponential form; e; ln; Background Tutorials. Exponential Functions.
Whatever the log form equation equaled becomes the exponent, and vice versa. Using the relationship, we can easily see how by looking at a log form equation, we can convert it to exponential form. Simply by moving the corresponding parts of the log form equations into b E = N {b^E} = N b E = N format, you can find the exponential form of log ...
We read a logarithmic expression as, “The logarithm with base b of x is equal to y,” or, simplified, “log base b of x is y.”We can also say, “b raised to the power of y is x,” because logs are exponents.For example, the base 2 logarithm of 32 is 5, because 5 is the exponent we must apply to 2 to get 32.
Book a Free Consultation Conclusion. Logarithmic form and exponential form are two ways of expressing the same mathematical relationship, typically involving exponential functions.The relationship between the exponential and logarithmic forms is based on the properties of logarithms.. Specifically, the logarithm of a number with a given base is the exponent to which the base must be raised to ...
Convert the following logarithmic form to exponential form: (i) log 3 81 = 4 Solution: log 3 81 = 4 ⇒ 3 4 = 81, which is the required exponential form. (ii) log 8 32 = 5/3 Solution: log 8 32 = 5/3 ⇒ 8 5/3 = 32 (iii) log 10 0.1 = -1 Solution: log 10 0.1 = -1 ⇒ 10-1 = 0.1. 3. By converting to exponential form, find the values of following:
Evaluating the Logarithm of a Reciprocal. Evaluate without using a calculator. Solution. First we rewrite the logarithm in exponential form: . Next, we ask, "To what exponent must 3 be raised in order to get ?" We know , but what must we do to get the reciprocal, ? Recall from working with exponents that . We use this information to write ...
log 6 216 = 3. Exponential form : 216 = 6 3. Example 6 : Obtain the equivalent exponential form of the following. log 9 3 = 1/2. Solution : Given logarithmic form : log 9 3 = 1/2. Exponential form : 3 = 9 (1/2) Example 7 : Obtain the equivalent exponential form of the following. log 5 1 = 0. Solution : Given logarithmic form : log 5 1 = 0 ...
Logarithmic to Exponential Form Logarithmic functions are inverses of exponential functions . So, a log is an exponent ! y = log b x if and only if b y = x for all x > 0 and 0 < b ≠ 1 . Example 1: Write log 5 125 = 3 in exponential form. ...
Every equation that's in exponential form has an equivalent logarithmic form and vice versa. For example, the y = b x is equivalent to x = log b . Both equations have a b , the base, an x , and a y .
Rewriting a logarithm in exponential form can make solving easier. In this tutorial, you'll see how to take a logarithm and rewrite it in exponential form!
