    Finding the Limit of ln((2x)^(2x))/(3x²+1) with x→∞

    Homework Statement find the following limit: ln((2x)^(2x))/(3x²+1) with x>infinity. The Attempt at a Solution I tried the following: lim ( ln((2x)^(2x))/(3x²+1) ) with x>infity = lim ( (3x²+1)/ln((2x)^(2x)) ) with x>0 lim 2xln(2x) with x>0 = 0, therefore lim...
