log 30 means 10^X=30. X = 1.477 Think about this - 10^1 =10 10^2=100 now, 10^.5 is the square root of 10 ...

log x(x-1)=log 30 x(x-1)= 30 x^2-x = 30 x^2-x-30 = 0 (x+5)(x-6) = 0 x = {-5. 6} we can throw out the ...

log(12) = log(2*2*3) = log(2) + log(2) + log(3) Now we just have to replace these three logarithms with the decimals you were given for them and them add them together. (I'll leave the rest for you to finish. log(5) 5 is not a product of any combination of 2's and/or 3's. Nor is it quotient or power of any combination of 2's or 3's.

You can put this solution on YOUR website! log(30/16) - 2log(5/9) + log(40/243) = = log(1) = 0. = log(1) = 0.

Question 152880: 10 log .55 = ? 10 log .30 = ? thank you Answer by jim_thompson5910(35256) (Show Source):

6^3x = 30 3xlog 6 =log 30 3x =(log 30)/(log 6) x =(log 30)/(3*log 6) x = .63275 check:6^3*.63275=30
