Question 34362: I would really appreciate if someone could help me these are the only problems that i didnt know how to do if someone could help me i would appreciate it
Solving Exponential Equations Using Logarithms round to 3 decimal place
2x = 30
5x - 1 = 3x
3.53x + 1 = 65.4
16x - 4 = 33 - x
7x - 2 = 5x

Answer by mukhopadhyay(490) About Me  (Show Source):
You can put this solution on YOUR website!
2x = 30
=> log(2x) = log(30)
=> log 2 + log x = log 30
=> log x = log 2 - log 30 = log (2/30) = log (1/15)
=> x = 1/15 = .067
Follow the same procedure as above to solve the rest of the problems. Shoot an email if you have difficulties.
