1. The problem statement, all variables and given/known data Find the derivative of: y = 10^(1 - x^2) 2. Relevant equations I get: y' = (10^(1 - x^2))(ln 10)(-2x) doing everything Wolfram does here: http://www.wolframalpha.com/input/?i=derivative+10^(1+-+x^2) I don't understand why it simplifies to Wolfram's final answer from what I got. 3. The attempt at a solution Everything Wolfram does above.
