Answer 1

Explicação passo-a-passo:

$s)~~({2\over3})=\\ \\ t)~~(-{3\over4})^{-4}=(-{4\over3})^4=+{256\over81}\\ \\ u)~~({1\over5})^{-1}=({5\over1})^1=5\\ \\ v)~~({1\over3})^{-2}=({3\over1})^2=9$

------------------------------

$2)\\ a)~~2^6=64\\ \\ b)~~(-2)^6=+64\\ \\ c)~~2^5=32\\ \\ d)~~(-2)^5=-32\\ \\ e)~~3^2=9\\ \\ f)~~(-3)^3=-27\\ \\ g)~~3^3=27\\ \\ h)~~(-3)^3=-27\\ \\ i)~~(-4)^{-4}=(-{1\over4})^4=+{1\over256}\\ \\ j)~~(-{1\over4})^{-1}=(-{4\over1})^1=-4\\ \\ k)~~({2\over3})^{-3}=({3\over2})^3={27\over8}\\ \\ l)~~(-{2\over3})^{-3}=(-{3\over2})^3=-{27\over8}$
