How do you find the inverse log using a TI 84 plus?
The 2nd function of the log button is the inverse log. Press 2nd log, which displays 10^( on the screen. Put a number after the opening parenthesis.
What is a logarithm?
log_a (b) [in words - log a of b], is like asking - what power of a equals b. For example: log_10 (100) = 2 because 10^2 = 100 log_2 (16) = 4 because 2^4 = 16
Are inverse and power of -1 the same?
Sometimes. The inverse of y sin x is y sin-1x, the inverse of a number is one divided by the number, also called the reciprocal of the number, y x, then y-1 x-1 1/x. However, the inverse logarithm of a given number is the number whose logarithm is the given number. Log of 1000 is 3 and 1000 is inverse log 3.
What is the inverse operation of multiplying by 2?
The inverse of multiplying is dividing, so dividing by 2.
Log x plus log 2 equals log 2?
log(x) + log(2) = log(2)Subtract log(2) from each side:log(x) = 0x = 100 = 1
Inverse log of - 0.123?
inverse log of -2.6
How do you use inverse log on graphing calculator?
The inverse of a logarithmic function is an exponential function. So to find the "inverse" of the log function, you use the universal power key, unless you're finding the inverse of a natural log, then you use the e^x key.
Inverse logs on TI-83 plus?
To get the inverse log function, press 2ND and then choose 10x. (Above LOG.) To get the inverse of a natural log function, press 2ND and then choose ex. (Above LN.)

The 2nd function of the log button is the inverse log. Press 2nd log, which displays 10^( on the screen. Put a number after the opening parenthesis.
How are exponential and log functions related?
One is the inverse of the other, just like the arc-sine is the inverse of the sine, or division is the inverse of multiplication.
How do you find the inverse log of a number using windows calculator?
The calculator won't do it.On the calculator, the button marked 10x gives youthe inverse log of the number in the window.
What is a logarithm?
log_a (b) [in words - log a of b], is like asking - what power of a equals b. For example: log_10 (100) = 2 because 10^2 = 100 log_2 (16) = 4 because 2^4 = 16
How do you add decibels?
The decibel is the common measure of sound intensity You can either use logarithmic calculators to add together two decibel values or you can ... ? 10 log (10x inverse log dBvalue/10 + 10x inverse log dBvalue/10) =
Give an example of an exponential function Find this exponential function's inverse which will be a logarithmic function Plot the graph of both the functions?
An exponential function can be is of the form f(x) = a*(b^x). Some examples are f1(x) = 3*(10^x), or f2(x) = e^(-2*x). Note that the latter still fits the format, with b = e^(-2). The inverse is the logarithmic function. So for y = f1(x) = 3*(10^x), reverse the x & y, and solve for y:x = 3*(10^y)log(x) = log(3*(10^y)) = log(3) + log(10^y) = log(3) + y*log(10) = y*1 + log(3)y = log(x) - log(3) = log(x/3)The second function: y = e^(-2*x), the inverse is: x = e^(-2*y).ln(x) = ln(e^(-2*y)) = -2*y*ln(e) = -2*y*1y = -ln(x)/2 = ln(x^(-1/2))See related link for an example graph.
What is the inverse of the function y equals log 5 x?
log5x
How do you find the inverse of logbX?
b^x In general the log and the exponential are inverses.
What is the inverse of y equal the log of 2x?
y = log 2x → x = 1/2 <base of log>y So: y = log102x → x = 1/210y (common logs) y = loge2x → x = 1/2ey (natural logs)
