bob bundy, thx for ur quick reply
I meant this
I know the steps, what I dont know is how to compute thiscoz this is where I was stuck! so is it equals to 0 (zero)?
if not, can you show me the last steps till we get only "2" at the end by canceling or subtracting .. -->
annd can you tell me where can i find how to deal with exponents and natural log by learnin some rules/law about them
really big help if u show me the way!
