Answer 1

1)(1/3)^5=(1^5)/(3^5)=1/243
2)(3/7)^3=(3^3)/(7^3)=27/343
3)(1 2/5)^2=(7/5)^2=(7^2)/(5^2)=49/25= 1 24/25= 1,96
4)(3 1/4)^2=(13/4)^2= (13^2)/(4^2)= 169/16= 10 9/16

Answer 2

$displaystyle 1)..( frac{1}{3})^{5}= frac{1}{3^{5}}= frac{1}{243}; \ \ 2)..( frac{3}{7})^{3}= frac{3^{3}}{7^{3}}= frac{27}{343}; \ \ 3)..(1 frac{2}{5})^{2}=( frac{7}{5})^{2}= frac{7^{2}}{5^{2}}= frac{49}{25}=1,96 \ \ 4)..(3 frac{1}{4})^{2}= (frac{13}{4})^{2}= frac{13^{2}}{4^{2}}= frac{169}{16}=10 frac{9}{16}=10,5625$
