Unformatted text preview: ure that you square the “-10” and not just the 10 (i.e. don’t forget the minus sign…). Second, in the final step, the 100 stays in the numerator since there is no negative exponent on it. The exponent of “-11” is only on the z and so only the z moves to the denominator. [Return to Problems] (c) n -2 m 7 m-4 n -3 This one isn’t too bad. We will use the definition of negative exponents to move all terms with negative exponents in them to the denominator. Also, property 8 simply says that if there is a term with a negative exponent in the denominator then we will just move it to the numerator and drop the minus sign. So, let’s take care of the negative exponents first. n -2 m m 4 n3 m = 7 m-4 n -3 7n 2 Now simplify. We will use property 1 to combine the m’s in the numerator. We will use property 3 to combine the n’s and since we are looking for positive exponents we will use the first form of this property since that will put a positive exponent up in the numerator. n -2 m m5 n = 7 m -4 n -3 7 Again, the 7 will stay in the denominat...
