Not necessarily the answer, just confused as to what the question is asking me! So if possible steps to arrive at the answer would be much appreciated! Thank you! rewritten: simplify...

Please explain the steps on how to figure this problem out.

in 2000, a company had 1145 stores nationwide. By 2002, this total had grown to 1535. If the number of stores continues to grow exponentially at the same rate, how many stores will there be in 2016 Exponential...

Suppose a retired professor who lives next door offers to pay you to work for him for the next 30 days. He says he will pay you $500 per day (option 1), or if you would like, he will pay you $0.01...

I have to find x! Can you help me lg= logarithm

Suppose that ln 2 = a and ln 5 = b. Use properties of logarithms to write each logarithm in terms of a and b. ln 10 ln7√20

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

15^9x=13^-x-7 write the exact answer using base -10 logarithm

Having trouble solving equation

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...

Its equivalent logarithmic form is logbx=y b = x = y =

The pH of a solution ranges from 0 to 14. An acid has a pH less than 7. Pure water is neutral and has a pH of 7. The pH of a solution is given by pH = - log x where x represents the concentration...

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...

I have to expand and simplify the logarithm log2(8x)

Log11m^7-33=-20

approximate logb 15b given that logb3≈2 and logb5≈5

The dollar value of two investments after t years is given by: f(t)=1800⋅1.055tf(t)=1800⋅1.055t g(t)=9500⋅1.041tg(t)=9500⋅1.041t Solve the equation f(t)=g(t)f(t)=g(t). What...
