That refers to the logarithm function. Since the base is not specified, the meaning is not entirely clear; it may or may not refer to the logarithm base 10.

If y equals 10 then what is then what is y equals log x?
y = 10 y = log x (the base of the log is 10, common logarithm) 10 = log x so that, 10^10 = x 10,000,000,000 = x
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.
Y equals log x If y equals 10 then what is x?
y=logx y=10 logx= 10 10logx = 10log1 logx = log1 x = 1 //NajN
The log of a quotient is the log of a numerator divided by the log of the denominator?
No. The log of a quotient is the log of a denominator subtracted from the log of the numerator.
What is log log scale?
A log-log scale is a set of axes where each axis is logarithmic in scale.
If 3 log x - 2 log y?
1
What are 3 logarithmic properties?
log(1) = 0log(x*y) = log(x) + log(y)If logb(x) = y then x = by.
The log of a quotient is the log of the numerator divided by the log of the denominator?
Not quite. The log(x/y) = log(x) - log(y) In words, this reads "The log of a quotient is the difference of the log of the numerator and the log of the denominator."
Log of square root of y?
log of the square root of 'y' = 1/2 sqrt(y)
Rules of log?
Here are a few, note x>0 and y>0 and a&b not = 1 * log (xy) = log(x) + log(y) * log(x/y) = log(x) - log(y) * loga(x) = logb(x)*loga(b) * logb(bn) = n * log(xa) = a*log(x) * logb(b) = 1 * logb(1) = 0
If y equals 10 then what is then what is y equals log x?
y = 10 y = log x (the base of the log is 10, common logarithm) 10 = log x so that, 10^10 = x 10,000,000,000 = x
How do you do log math problems?
Sometimes you need to take logs, or antilogs, on both sides of an equation. Sometimes you need to apply certain common logarithmic identities, especially: log(xy) = log x + log y log (x/y) = log x - log y log (ab) = b log a
What is the definition of log?
log base m of x = y is equivalent to x=m^y
What is gernal value of log y?
Log(y) can be any number, positive or negative, no limits. It all depends on the value of 'y'.
What is the difference between an anti-log and an exponential?
let x and y be two numbers ex = y log y = x antilog x = y
How do you solve equations with exponents with y?
Do you mean y=x^2.5? I you had y=13^2.77, it's easier to use log. log y=2.77*log13 ~ 3.0856. 1217.9 is the antilog and answer.x=1217.9 But math can be more complicated. How about y^2.5=x^1.8. Logs really shine here. Take log of both sides. 2.5*log y = 1.8 log x. Say x=100 and 1.8 log 100 = 1.8*2=3.6. We have 2.5 log y = 3.6 and log y = 3.6/2.5 = 1.44. Now y = antilog 1.44=27.54229. So does 27.54229^2.5 = 100^1.8 ? Yes it does.
Rewrite the folling as a logarithmic expression b y equals x?
