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)

Answer by fractalier(6550)   (Show Source):
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
