Last class we learned more about logarithms."The Change of Base Therom" the last log law.
logb^n=loga^n/logab
ex) heres a little rule
log (x + 3) = IS ABSOLUTELY NOT- logx + log3
instead, it becomes:
log(2(3^x)) = log5
log2 + log3^x = log5
log2 + x * log3 = log5
x * log3 = log5 - log2
x = log5 - log2 / log3
x = .8340437671
