Question 38390This question is from textbook  
:  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
