Best ResponseYou've already chosen the best response.0ok, let's say you want to find log 12 (i'm assuming it's base 10?) we can write this as \[\log(1.2*10^1)=\log(1.2)+\log(10^1)=\log(1.2)+1\] that first step is an important rule with logarithms. Now, if you have a table, let's find 1.2 on it. It's probably broken down into sections based on the first digit or two, and then you have to read across. There's probably a 1.2 row, so you look in that row and go over to the 0 column; this means you're finding the log of 1.20, which is clearly the same as 1.2 since i'm not sure what your table is like, try it and tell me if that's how it's set up. If not, describe it to me (or link)

Best ResponseYou've already chosen the best response.0sweet, then all you do is take that number and add 1 to it. similarly, for log 0.038, you put it in scientific notation, break it up like I did, and then find the value of 3.8 in the log table, then add.

Best ResponseYou've already chosen the best response.0so for 1.2 it would = 0.0792

Best ResponseYou've already chosen the best response.0so do i move the decimal once or twice because you broke 0.038 into 3.8 and 12 into 1.2

Best ResponseYou've already chosen the best response.0you move it as many times as necessary to make it so that there is one digit to the left of the decimal point. Then, the exponent on the ten becomes the number of places you moved it. If you move it to the left, the exponent, is positive, and if it's to the right, it's negative.

Best ResponseYou've already chosen the best response.0well, how many places would you have to move the decimal point to make it so that exactly 1 digit is on the left side of it?

Best ResponseYou've already chosen the best response.0that's 4, not 1... you go to the 2.1 row, then over to the 1 column
