no it wanted the calculator total that was supposed to come to -3.6380 You are supposed to condense the problem down, something like this

ln8^-2 - ln7^2/ln8^2 - ln7

only the ^-2 part is wrong, that is were I need help, figuratively speaking you would then do the next part, which is to use all the powers.

ln8^-2 would be = ln 0.015625 (wrong I know but I did say figuratively)

ln7^2= ln 49

then the bottom part of the fraction would be

ln8^2= ln64

ln7 would remain the same.

then you would put it all back together and it would look something like this.

ln0.015625-ln49/ln64-ln7

then you wold take the top and divide the two then do the same with the bottom, and then you would be ready to put it into the calculator. I have no idea what I'm talking about really this is just what I sow on the "helpful" similar problem video that accompanies the homework problem. they pass steps though and those are usually the steps I need.
