1.Calcule:
[tex]A)7^{2} =49\\D)8^{0} =1\\G)(-1)^{32} =1^{32}=1\\J)(\frac{3}{4})^{2} =\frac{3^2}{4^2}=\frac{9}{16}\\[/tex] [tex]B)4^{3} =64\\E)(-9)^{1} =-9]\\H)(+5)^{3}=125\\K)\left(\frac{2}{3}\right)^{-3}=\frac{1}{\left(\frac{2}{3}\right)^3}=\frac{1}{\frac{8}{27}}=\frac{27}{8}[/tex] [tex]C)3^4=81\\F)\left(-0.5\right)^0=1\\I)-\left(-2\right)^4=-16\\L)\left(\frac{4}{5}\right)^{-2}=\frac{25}{16}[/tex]
2.CALCULE O VALOR DAS EXPRESSÕES:
[tex]A)26-5^2=26-25=1\\B)10-\left(-2\right)^3=10-\left(-8\right)=18\\C)32+\left(-3\right)^3=32-27=5\\D)\left(-2\right)^4+\left(-4\right)^2=16+16=32\\E)\left(-2\right)^3+\left(-1\right)^9=-8-1=-9\\F)7-\left(-3\right)^2+1=7-9+1=-1[/tex]
