Resolvamos

1.

(4/5)⁶× (4/5)-⁵

$(\frac{4}{5}) ^{6-5} \\\\\(\frac{4}{5})^{1} \\\\= (\frac{4}{5})$

2.

(a+b)⁹ ÷ (a+b)⁷

$\frac{(a+b)^{7} (a+b)^{2} }{(a+b)^{7}} \\\\=(a+b)^{2}$

3.

[(1/3)²]⁶

$(\frac{1}{3} )^{2*6} \\\\\frac{1}{3}^{12} \\\\\frac{1^{12} }{3^{12} } \\\\=\frac{1}{3^{12} }$

4.

[(1/4)³]⁴

$(\frac{1}{4} )^{3*4} \\\\(\frac{1}{4} )^{12} \\\\(\frac{1^{12} }{4^{12} } )\\\\= \frac{1}{4^{12} }$

5.

(2/3)-³

$\frac{1}{\frac{1}{4}^{3} } \\\\\frac{1}{64} \\\\\frac{1}{\frac{1}{64} } \\\\= 64$
