\frac{11}{13}

a^4\cdot b^3

4x^{\frac{5}{12}}

8

 - 5\sqrt{2}

0.4

Paso a paso:

\frac{\frac{8}{9} -\frac{2}{27}}{\frac{8}{9} +\frac{2}{27}}

= \frac{\frac{24}{27} -\frac{2}{27}}{\frac{24}{27} +\frac{2}{27}}

= \frac{\frac{22}{27}}{\frac{26}{27}}

=\frac{22(27)}{26(27)}

=\frac{22}{26}

= \frac{11}{13}

_________________________________________

\frac{ab^{-1}}{(ab)^{-1}}\cdot \frac{a^2b}{b^{-2}}

= \frac{ab^{-1}}{a^{-1}b^{-1}}\cdot \frac{a^2b}{b^{-2}}

= a^{1-(-1)}b^{-1-(-1)}\cdot a^2b^{1-(-2)}

= a^{2}b^{0}\cdot a^2b^{3}

= a^{2+2}\cdot b^{0+3}

 = a^{4}\cdot b^{3}

_________________________________________

\frac{x^{\frac{1}{3}}(8x)^{-\frac{2}{3}}}{x^{-\frac{3}{4}}}

 = x^{\frac{1}{3} - (-\frac{3}{4})}(\sqrt[3]{8})^2 x^{-\frac{2}{3}}

 = x^{\frac{13}{12}} 2^2 x^{-\frac{2}{3}}

 = 4 x^{\frac{13}{12} - \frac{2}{3}}

= 4 x^{\frac{5}{12}}

_________________________________________

[\frac{(27)^{\frac{4}{3}}-(27)^0}{(3^2+4^2)^{\frac{1}{2}}}]^{\frac{3}{4}}

= [\frac{27(27)^{\frac{1}{3}}-1}{(9+16)^{\frac{1}{2}}}]^{\frac{3}{4}}

= [\frac{27(3)-1}{\sqrt{25}}]^{\frac{3}{4}}

= [\frac{81-1}{5}]^{\frac{3}{4}}

 = [\frac{80}{5}]^{\frac{3}{4}}

 = 16^{\frac{3}{4}}

= (\sqrt[4]{16})^3

 = 2^3

=8

_________________________________________

\sqrt[4]{64}-\sqrt{50}-\sqrt[6]{512}

= \sqrt[4]{16\cdot 4}-\sqrt{25\cdot 2}-\sqrt[6]{64\cdot 8}

= \sqrt[4]{2^4\cdot 4}-\sqrt{5^2\cdot 2}-\sqrt[6]{2^6\cdot 8}

 = 2\sqrt[4]{4}-5\sqrt{2}-2\sqrt[6]{8}

= 2\sqrt[4]{2^2}-5\sqrt{2}-2\sqrt[6]{2^3}

= 2\sqrt{2}-5\sqrt{2}-2\sqrt{2}

 =-5\sqrt{2}

_________________________________________

\sqrt[3]{0.1-0.036}

=\sqrt[3]{0.064}

=\sqrt[3]{64 \cdot 10^{-3}}

=\sqrt[3]{64}\sqrt[3]{10^{-3}}

=\sqrt[3]{4^3}10^{-1}

=4(10^{-1})

=0.4
