You can't take the log of the left side of the equation as you have done. Log ( a+b) does not equal log a + log b. 3^x - 4^y = 5 3^(x+1) + 4^y = 23 add these equations 3^x + 3^(x+1) = 28 3^x + 3*3^x = 28 4*3^x = 28 3^x = 7 xlog3 = log7 x = log7/log3 = 1.77124 ~ 1.77 3^x - 4^y = 5 3^1.77124 - 4^y = 5 7 - 4^y = 5 4^y = 12 y log(4) = log(12) y = log(12)/log(4) = 1.79248 ~ 1.79.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
