Given to simplify:
.
%283x%5E%28-5%29%29%2F%282x%5E3%29
.
You got the answer correct if you meant it to be interpreted as:
.
3%2F2x%5E8
.
You correctly recognized that you divide the two in the denominator into the 3 in the numerator. Then, if you recognized that in this problem the x term in the denominator x%5E3 is the divisor and the x term in the numerator x%5E%28-5%29 is the dividend and when you divide these two you subtract the exponent 3 of the divisor from the exponent -5 of the dividend to get the answer x%5E%28-5-3%29+=+x%5E%28-8%29%29%29.
.
So the answer to the problem could have been written as:
.
%283%2F2%29x%5E%28-8%29 which is equivalent to %283x%5E%28-8%29%29%2F2
.
And by the rules of exponents, you can put the x term in the denominator, but in doing so its exponent changes sign. In this case the answer can be written as the answer that you got. Namely as:
.
3%2F%282x%5E8%29
.
Hope this helps you to gain some further understanding of and confidence in the method that you used in working this problem. Good job!!! Keep it up!!!
