Question

Помогите пожалуйста с решением ​

Answer 1

$1)\frac{5^{6}}{5^{4} }=5^{6-4}=5^{2}=25\\\\2)\frac{9^{12}}{9^{11}}=9^{12-11}=9\\\\3)\frac{0,8^{5} }{0,8^{3}}=0,8^{5-3}=0,8^{2}=0,64$

$4)\frac{(-1\frac{1}{2})^{4}}{-1\frac{1}{2}}=(-1\frac{1}{2})^{4-1}=(-1\frac{1}{2})^{3}=(-1,5)^{3}=-3,375\\\\5)\frac{(\frac{2}{3})^{7}}{(\frac{2}{3})^{4}}=(\frac{2}{3})^{7-4}=(\frac{2}{3})^{3}=\frac{8}{27}\\\\6)(1,3)^{9} :(\frac{13}{10})^{7}=1,3^{9}:1,3^{7}=1,3^{9-7} =1,3^{2}=1,69$
