Answer 1

1)

$\frac{(-5)^{6}*(-5)^{7}*(-5)^{8}}{(-5)^{14}*(-5)^{4}}=\frac{5^{6}*(-5)^{7}*5^{8}}{5^{14}*5^{4}}=\frac{-5^{6+7+8}}{5^{14+4}} =-\frac{5^{21}}{5^{18}} =-5^{21-18}=-5^{3}=-125$

3)

$\frac{(\frac{1}{3})^{10}* (\frac{1}{3})^{20}*(\frac{1}{3})^{30}}{(\frac{1}{3})^{34}*(\frac{1}{3})^{23}} =\frac{(\frac{1}{3})^{10+20+30}}{(\frac{1}{3})^{34+23}}=\frac{(\frac{1}{3})^{60}}{(\frac{1}{3})^{57}}=(\frac{1}{3})^{60-57} =(\frac{1}{3})^{3}=\frac{1}{27}$
