4 Place the roast fat side up and rib bones down in a roasting pan. Insert a meat thermometer into the thickest part of the roast, making sure that the thermometer isn't touching a bone. 5 After browning the roast at a 500Â°F temperature in the oven for 15 minutes, reduce the oven temperature to 325Â°F.

Best Answer: log 0 is impossiible .It's not defined.It's like 0/0. e raise to the power infinity is also not defined However log 0 can be any real value and e raise to the power infinity is infinity. just like we say 6/0 =infinity.Source(s): Super Ego.ating Newest Oldest.

Negative infinity is not a number, so e raised to the power of negative infinity is nothing. What you want to know is Â«why is $\lim\limits_{x\to-\infty}e^x=0$?Â». â Mariano Suarez-SuÃ¡rezâ¦ Alvarez mar 16 at:3. 05. The principle root of a positive number raised to any real power (positive or negative) is positive. Consider the phrase more as $\lim\limits_{n\to -\infty} e^{n} = \lim\limits_{n\to\infty} e^{-n} = \lim\limits_{n\to\infty}\frac{1}{e^n}$.
