log AB^2 log A+log B+log2
-1.958607315
0.0706
A logarithm of a reciprocal. For example, log(1/7) or log(7-1) = -log(7)
The value of log o is penis
the value of log (log4(log4x)))=1 then x=
acording to me the value is 0 because the value of log 1 at any base is always 0.
Zero!
log (short for logarithm) does not actually have a value. It is actually an operation. So if you see log(10), for instance, you need to take the logarithm of the number in the parenthesis. To do that, just ask yourself "ten raised to WHAT POWER equals the number inside the parenthesis?" And log(#) = that exponent. To finish the example above, log(10) asks you 10? = 10. The answer here is 1, so log(10)=1.

I know the answer *is arctan(x), but how about breaking it into partial fractions by doing 1/(1-ix)(1+ix)?
If it is compounded annually, then: F = P*(1 + i)^t {F is final value, P is present value, and i is interest rate, t is time}.So if it triples, F/P = 3, and 12 years: t = 12, so we have 3 = (1 + i)^12, solve for i using logarithms (any base log will do, but I'll use base 10):log(3) = log((1+i)^12) = 12*log(1+i)(log(3))/12 = log(1+i).Now take 10 raised to both sides: 10^((log(3))/12) = 10^log(1+i) = 1 + ii = 10^((log(3))/12) - 1 = 0.095873So a rate of 9.5873 % (compounded annually) will triple the investment in 12 years.
log(0.99) = -0.004364805
The numeric value of log(x) is the power you have to raise 10 to in order to get 'x'.
