logarithm of 100 = 2. If there is not a subscript number on your log, you assume it to be 10. In other words, the little subscript would be the base if you were raising it to a power, and the big number is the answer of the power. For example, log (base 10) 100 = 2 because 10 (the base) raised to a power of 2 (the log answer) = 100 (the number you just took the log of.)
natural log
log x + 2 = log 9 log x - log 9 = -2 log (x/9) = -2 x/9 = 10^(-2) x/9 = 1/10^2 x/9 = 1/100 x= 9/100 x=.09
You can rewrite the equation as... 100=10x X=2
Yes. Logarithms to the base 10 are called common logarithms, and 2 is the correct common logarithm for 100.
log 100 base e = log 100 base 10 / log e base 10 log 100 base 10 = 10g 10^2 base 10 = 2 log 10 base 10 = 2 log e base 10 = 0.434294 (calculator) log 100 base e = 2/0.434294 = 4.605175

The log or logarithm is the power to which ten needs to be raised to equal a number. Log 10=1 because 10^1=10 Log 100=2 because 10^2=100 Sometimes we use different bases. Like base 2. Then it is what 2 is raised by to get the number. Log "base 2" 8=3 because 2^3=8
2 log(x) + 3 log(x) = 105 log(x) = 10log(x) = 10/5 = 210log(x) = (10)2x = 100
You can rewrite the equation as... 100=10x X=2

inverse log of 2= 1/(log{10}2)= 1/(log2)=1/0.3010299=3.3219. hence answer is 3.3219
Yes. Logarithms to the base 10 are called common logarithms, and 2 is the correct common logarithm for 100.
log is short for logarithm log(base a)x=y is the same as saying a^y=x Normal log is base 10. So if you see log with no subscript after it, it is log base 10. So when you press the log button on your calculator and put a number after it you are asking 10 to what power =100? And 10 to the second power = 100 so you will get an answer of 2. A log (base 5)625 you would be asking, 5 to what power is equal to 625? The answer is 4 because 5^4=625 Logarithms are used to simplfy complex calculations. The Richter scale for measuring earth quakes is expressed in the form of a logarithm. A increase of 1 on the scale means an increase of 10 times.
"Log" is short for Logarithm and can be to any base.The Logarithm of a number is the number to which the base has to be raised to get that number; that is why there are no logarithms for negative numbers. For example: 10² = 100 → log to base 10 of 100 is 2.There are two specific abbreviations:lg is the log to base 10ln is the log to base e - e is Euler's number and is approximately 2.71828184; logs to base e are known as natural logs.On an electronic calculator the [log] button takes logarithms to base 10. The inverse function (anti-log) is marked as 10^x.Similarly the [ln] button takes logs to base e, with the inverse function marked as e^x.
