 :  Please help me with these four questions in the review section.
 Find the value of v in each equation.
 18. log(27) 3=v
 20. log(4) 1/16=v
 Write each expression as a single logarithm. Then simplify, if possible
 24. log(5) 3 + log(5) 6 + log(5)
 25. log 6 - log 3 + 2 log 7
 Note:  (number in para is the base)

You can put this solution on YOUR website! For log(27) 3 = v, it becomes 27^v = 3 and v = 1/3 For log(4) 1/16 = v, it becomes 4^v = 1/16 and v = -2
 Cannot do log(5) 3 + log(5) 6 + log(5) ??? because of the missing piece, but
 log 6 - log 3 + 2 log 7 = log (6/3 * 7^2) = log 98
