Then what we want to prove is that p = q+r Those three logarithm equations by definition of logarithms are equivalent respectively to these three exponential equations: 10 p = ab, 10 q = a, 10 r = b Multiply the last two equation (multiply equals by equals): 10 q 10 r = ab Multiply on the left by adding exponents of 10: 10 q+r = ab But also 10 ...

2017年5月10日 · Hi, I'm looking for a visual proof log(ab) = log a + log b I've seen diagrams where the values are measured out, but it's not immediately obvious why this holds. Is there an intuitive way to illustrate this? Also, are there other functions with this property.

2006年11月12日 · log(a+b) help First Log(a+b) is Log(a+b), but if you want to solve a regular problem like this : Log 2 = 0.3 Log 3 = 0.48 (aprox) and you can´t use your calculator then Log 5 ? You must think in Log (3 + 2) but there´s no way to solve this way. Log (10/2) = Log 5 then using Logarithm fundamentals: Log 10 - Log 2 = 1 - log 2 = 1 -0.3 = 0.7

2006年4月20日 · A large log AB is 6 m long. It rests in a horizontal position on two smooth supports C and D, where AC = 1 m and BD = 1 m, as shown in Figure . David needs an estimate of the weight of the log, but the log is too heavy to lift off both supports.

You can put this solution on YOUR website! TRUE/FALSE: log (A-B)= log A divided by log B False. For example A = 100, B = 10

You can put this solution on YOUR website! if Log ((a+b)/2) = 1/2 (log a + log b), show that a = b log((a+b)/2) = (1/2)(log(a) + log(b))

Question 222790: Let (((log(a,X))))=C and (((log(b,X))))=D. Find the general statement that expresses (((log(ab,X))))in term of C and D. I already know the answer is (CD)/(C+D) I cannot figure out how to write a proof for this question. I know all of the logarithmic principles as well but I can only come up with either (C)(D) as my answer or (C+D).

Is log(ab)=log(a).log(b) a true statement? Choose any positive values for a and b and then compute both sides-----I don't know what log(a).log(b) means. log(ab) = log(a) + log(b) For example: log(100*1000) = log(100) + log(1000) 5 = 2 + 3-----log(21) = log(3) + log(7) 1.32222 = 0.47712 + 0.8451
