Here's the question you clicked on:
3psilon
Why is e^ lnx^3 equal to just x^3?
properties of logarithms... \[\huge e^{\ln a} \implies e^{\log_e a} \implies a\] do you remember this property?
e^(ln(x)) = x ln(e^x) = x They are inverse functions.
e is a inverse Function of ln so they cancles off....like \[\sin(\sin ^{-1} 7) = 7\]
you can;t take the arcsin of 7....
lol i suppose that's true :) Example gone bad... i hate when that happens XD
oh...Sorry.....Max value of sin is 1.....) hm...hm
