A strain of bacteria grows exponentially. Immediately after 2 hours there were 1000 bacteria, and immediately after three hours there were 5000 bacteria. If no bacteria die, then the time it takes...

You can't distribute the natural log? I don't understand.

Consider the equation log((x + 3)(x−8))+ log(x+3/x-8) = 2. (a) Explain why x = 7 is not a solution to this equation. (b) By combining the logarithms,...

This problem involves the Rule of 70, which gives quick estimates of the doubling time of an exponentially growing quantity. If r% is the annual growth rate of the quantity, then the Rule of 70 says Doubling...

Given that log_2(3) • log_3(4) • log_4(5)..... log_n-1(n) • log_n(n+1) = 10, find the value of n. NEED ANSWER ASAP

given that loga^2=0.693 , loga^6=1.792 , loga^5=1.609 find loga^60

e^2.4=11 write the equivalent logarithmic equation.

log x^(6/5)*y^(4/5) given that log x=2, log y =3. log 2 =0.3, and log 3=0.48 the answer is 24/5 but I dont know what to do after getting rid of the radical

So there's this question. It's 1/2log(25)+log(4). Then we convert it to log(25^1/2) + log (4). But then the log converts to the square root of 25 from log(25^1/2). Why? And what does that...

So, in all, I'm really just asking how I would use log in general. (Please answer in a 'for dummies' format please! :) Not exactly the best with the vocabulary!) Due to some research, I've learned...
