: hello, i am having trouble with this problem is says to simplify the expression and that your answer must be in fraction form. Also all exponents must be positive.
simplify: 3^-7 x^3 y^6/3^8 x^6 y^6


this is what i figured out so far:3^-7 x^3 y^6/3^* x^6 Y^6

3^7 x^3 x^6/ 3^8 This question is from textbook

Simplify:
3%5E%28-7%29x%5E3y%5E6%2F3%5E8x%5E6y%5E6 The 3%5E%28-7%29 can be put in the denominator as 3%5E7 and you can cancel the y%5E6's to leave you with:
x%5E3%2F%283%5E8%2A3%5E7%2Ax%5E6%29 Finally, add the exponents on the 3's 3%5E8%2A3%5E7+=+3%5E%28%288%2B7%29%29 and subtract the exponents on the x's x%5E3%2Fx%5E6+=+1%2Fx%5E%28%286-3%29%29 so that you end up with:
1%2F%283%5E15%2Ax%5E3%29 ...and if you have to evaluate: 3%5E15+=+14348907 your answer would be:
1%2F14348907x%5E3
