Question 30196: when a question asks you to show something algebraically, DO NOT substitute numbers for the variables and give me an example. On the other hand, when a question asks you to show something numerically or to provide an example, you may substitute numbers for the variables. Show all work
Solve for y: ln(y) + ln(2) = ln(ln(e2)).
Answer by sdmmadam@yahoo.com(530) (Show Source): You can put this solution on YOUR website!
Solve for y: ln(y) + ln(2) = ln(ln(e2)).
ln(y) + ln(2) = ln(ln(e^2)).
ln(y) + ln(2) = ln(2ln(e)). (using log base e(m^n) = n logbase e (m) )
ln(y) + ln(2) = ln(2). (since log base e (e) =1 and 2log(e) = 2X1 = 2 )
log (y) = log(2)-log(2) subtracting log(2) from both the sides
log(y) =0
That is y = (e)^0 (applying definition log base e (N) = p implies N= (e)^p)
That is y = 1
Answer: y = 1
Verification: can be done orally(using log(1) =0 )
