1. The problem statement, all variables and given/known data http://i51.tinypic.com/2zyfyaa.jpg Question 3 l ) 2. Relevant equations 3. The attempt at a solution (6a^-2b^-3)^2 (__________) 1/6a^2 * 1/b^3 / 1/2a^2 * 1/b^1 (2a^2b^-1 ) I multiplied the top half together to give me 1/ 36a^4b^2 Multiplied the bottom half to give me 1/4a^4b^1 , Then took the reciprical of the bottom half and move it up and multiplied it with the top half. Giving me a final of :: 4a^4b^1 __________ 36^a4b^5 However, when i fold this down it becomes 1/9 and the a's cancel and 4b is left over at the bottom. The answer is a^8b^4 / 9 I know its complicated to read, just write it on paper and ull understand. What did i do wrong?
