Solve the following logarithmic equation. Exact words only: log 3(x+4) = 2+log3(x-20) the 3 in the part of log (3)should be lower just didn't know how to type it in here

My teacher assigned us this problem: Using the following logarithms Log2,log3 and log10 solve for the log150,log 75 incorporating the properties of logarithms ,i tried ,but failed plz help!!

solve the following logarithmic equation. Be sure to reject any value of x that is not in thedomain of the orginal logarithmic expression. Give the exact answer. log3(x+8)=4 The three actually drops down a little below the g. Can someone tell me how to do this?

What is the domain and range of log3 (1-x)? I will be happy to critique your thinking. To assist you, consider log (-4) log (0) log 25 Those are to the base 10, changing to another base just changes the numbers, not the function.

how wod i solve the following two eqautions? either exactly or to 3 significant a)2^x = 5 b)3^x+1 = 7 i know a) is 2.32 and b) is 0.771 but i don't know how to show it out step by step in how i worked it out . can sum1 plz help me You have to use logs, and learn how to do that...

Algebra/can you help me
Write each expression in terms of common logarithms, and then give a calculator approximation (correct to four decimal places). log7^10= 1.183 How do you find the approximation log3^316 = 5.239 How do you find the approximation Thank you

i will be greatful to you if you help in solving the below problems: 1.)Prove that log15=log5+log3 2.)Show that log10800=4log2+3log3+2log5 3.)show that log108/605=2log2+3log3-log5-2log11.

Rewrite the following as an equivalent logarithmic equation.Do not solve. y^t = x answer logy+logt=logx-is this right also Express as an equivalent expression that is a sum of logt (3ab) the t is at the bottom of the g answer log3+loga+logb logarithms.

Let log 2 = a, log 3 = b and log 7 = c. Express the indicated logarithm in terms of a, b, and c. 1-log3 5 (3 is the subscript of the log) ans:(1-a)/b, i need someone to show me the step bcus my ans is different from the given ans. my ans=(1/a)-b.

Evaluate the logarithmic equation for three values of x that are greater than 2, three values of x that are between 1 and 2, and at x=2. Show your work. Use the resulting ordered pairs to plot the graph. State the equation of the line asymptotic to the graph. y = log3 (x - 1)

I am supposed to write each logarithmic expression as a single logarithm. I have logbase3of13 + logbase3of3 and my answer is logbase3of39. Can I simplify that any further? also logbase3 of 3 is 1 1+ log3 13 is another answer, simpler, to me. oh, okay, so it would make more ...
