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.

**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

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.

**Algebra**

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)
