10) [tex] \frac{ x^{13} }{ x^{2} }
13 -2 = 11,right? [/tex]
Your answer: [tex] x^{11} [/tex]
11) [tex] 4^{3} ( 4^{12} ) [/tex]
[tex] 2^{12}(^2) = 2^{24} [/tex]
Change it to: [tex] 2^{6} ( 6^{24} [/tex]
Your answer would have to be: [tex] 4^{36} [/tex]
12) It is similar to the steps with the one above this one, so therefore your answer would have to [tex] 3^{36} [/tex]
