Question 45133: I've been working on a problem but can't seem to find the solution to write as a single logarithm: 2 log 4 + log x - log 2.
My fisrt instict/ step was to: rearrange the problem to make it more clearer to work and went from there. I'm missing a step somewhere, any guidance would be greatly appreciated.
2 log 4 + log x - log 2
log 4^2 + log x - log 2
log 16 - log 2 + log x ?
log x = log 16 / log 2 ?
x = 8 ?

Question 45396: I need to write log3 (3/xysquared divided by w) in expanded form
note: Log3 is a small 3 at the bottom of the g, and I used the symbol / for the square root symbol. and the three in front of my square root symbol is in the index. So it would be the cubed root of xy with the y being squared.

Question 45492This question is from textbook
: I'm not sure how to set up this problem. The number before the x in the exponent expression on the #3 confuses me. The problem is 3^2x=4^x
I have set the problem up as 2xLog3=xlog4. The next step I believe is 2xLog3-xLog4=0, Factor out x. X(2log3-log4)=0. I don't know if this is right or what the next step would be. without the 2 in front of log 3 I would divide out the expression in the parenthesis to get x=0. Any help would be greatly appreciated thank you. TamaraThis question is from textbook
