a log is the 'undo-er' of powers, kind of like division is the 'undo-er' of multiplication. EX: 102 = 100, then log10(100) = 2 103 = 1000, then log10(1000) = 3, in this example, we are using log base 10, this is a default base and sometimes isn't even wirten. e is probably the most common base but log base e is more simply called the natural log, or ln. so in general: logx(m) = N means that xN = m so log5(125) = 3 because 53 = 125.
What is it
You have to use logarithms (logs).Here are a few handy tools:If [ C = D ], then [ log(C) = log(D) ]log(AB) = log(A) + log(B)log(A/B) = log(A) - log(B)log(Np) = p times log(N)
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" is not a normal variable, it stands for the logarithm function.log (a.b)=log a+log blog(a/b)=log a-log blog (a)^n= n log a
log(x) - log(6) = log(15)Add log(6) to each side:log(x) = log(15) + log(6) = log(15 times 6)x = 15 times 6x = 90

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
Exponent, expression, e (natural log)
in math, ln means natural log, or loge and e means 2.718281828
i am not in middle school but we use fast math you have to have your user name and a lunch pin for when we use fast math but yours might be differen t
For my school, you can go on a web site called Classzone.com and when you first get on you can pick a subject and state. The site will search for your book but you have to have a school code to first log on. If your school does have this site then you log on with the school username and password then make one of your own as you go on.
You can't solve this since it isn't an equation.There is also an ambiguity (it's hard to write math on a typewriter keyboard) - are we talking about log(x3) or maybe logx(3)?Restate the question: Simplify log(x3)Answer: 3log(x)You could explain this by saying: log(x3) = log[(x)(x)(x)] = logx + logx + logx = 3logx. The general rule is log(xn) = nlogx.
move the log then hang on the telephone poll then reach for target
YOU GO MATH BLASTER YOUR LOGIN NAME WILL BE ON THE LEFT then at the right top corner click log out next at the same corner click register and the sreen will have the register stuff for you and that is how you you register for math blaster. Your Welcomw Everybody who needs help registering for math blaster.!
You may find it at this link frankly though :l You need the teacher to log you on so when you forget your math textbook wich I have done :( it doesn't work to well
It requires math to figure out how maple timber is logged. You actually need to know an equation known as "log scales."
