1. Some math problems i cant seem to figure out? Part 2

5. Use the product, quotient, and power rules of logarithms to rewrite the expression as a single logarithm. Assume that all variables represent positives real numbers: 3 log lower case 2to (4x+6)+ 5 log lower case 2 to (3x-2)

6. Use the change of base rule to find the logarithm to four decimals places: log lower case 2 to 8

7. Solve the equation and express the solution in exact form: 1. 3^(x-1)=12 2. log(x+14)=2

8. Solve the equation. If necessary, round to the nearest thousandth: 3^(2x-1)=22

In my opinion all these questions are straight forward. So please, show us what you've done so far and tell us where you have difficulties to do these questions.
