Unformatted text preview: or since there isn’t a negative exponent on it. It will NOT © 2007 Paul Dawkins 6 http://tutorial.math.lamar.edu/terms.aspx College Algebra move up to the numerator with the m. Do not get excited if all the terms move up to the numerator or if all the terms move down to the denominator. That will happen on occasion. [Return to Problems] (d) 5 x -1 y -4 (3 y ) 5 -2 x9 This example is similar to the previous one except there is a little more going on with this one. The first step will be to again, get rid of the negative exponents as we did in the previous example. Any terms in the numerator with negative exponents will get moved to the denominator and we’ll drop the minus sign in the exponent. Likewise, any terms in the denominator with negative exponents will move to the numerator and we’ll drop the minus sign in the exponent. Notice this time, unlike the previous part, there is a term with a set of parenthesis in the denominator. Because of the parenthesis that whole term, including the 3, will move to the numerator. Here is the work for this part. 5 x -1 y -4 (3 y ) 5 -2 x9 = 5 (3 y5 ) xy 4 x 9 2 5 ( 9 ) y10 45 y 6 = = 10 xy 4...
