• Bom... vamos lá, baby!

$a) \: \: 81 {}^{ \frac{1}{4} } + 81 {}^{ - \frac{1}{4} } \\ \\ (3 {}^{4} ) {}^{ \frac{1}{4} } + 81 {}^{ - \frac{1}{4} } \\ \\ (3 {}^{4} ) {}^{ \frac{1}{4}} + \frac{1}{81 {}^{ \frac{1}{4} } } \\ \\ 3 + \frac{1}{81 {}^{ \frac{1}{4} } } \\ \\ 3 + \frac{1}{(3 {}^{4} ) {}^{ \frac{1}{4} } } \\ \\ 3 + \frac{1}{3} \\ \\ \frac{9 +1 }{3} \\ \\ {\red{ \frac{3}{10} }}$

$b) \: \: 8 {}^{ \frac{1}{3} } \times 125 {}^{ \frac{2}{3} } \\ \\ (2 {}^{3} ) {}^{ \frac{1}{3} } \times 125 {}^{ \frac{2}{3} } \\ \\ (2 {}^{3} ) {}^{ \frac{1}{3} } \times (5 {}^{3} ) {}^{ \frac{2}{3} } \\ \\ 2 \times (5 {}^{3} ) {}^{ \frac{2}{3} } \\ \\ 2 \times 5 {}^{2} \\ \\ 2 \times 25 \\ \\ {\red{50}}$

$c) \: \: 343 {}^{ \frac{4}{3} } \div 49 {}^{0.5} \\ \\ (7 {}^{3} ) {}^{ \frac{4}{3} } \div 49 {}^{0.5} \\ \\ 7 {}^{4} \div 49 {}^{0.5} \\ \\ \frac{7 {}^{4} }{49 {}^{0.5} } \\ \\ \frac{7 {}^{4} }{(7 {}^{2} ) {}^{0.5} } \\ \\ \frac{7 {}^{4} }{(7 {}^{2}) {}^{ \frac{1}{2} } } \\ \\ \frac{7 {}^{4} }{7} \\ \\ {\red{7 {}^{3} }} \: ou \: {\red{343}}$

$d) \: \: 36 {}^{ \frac{3}{2} } - 32 {}^{ \frac{2}{5} } \\ \\ (6 {}^{2} ) {}^{ \frac{3}{2} } - 32 {}^{ \frac{2}{5} } \\ \\ (6 {}^{2} ) {}^{ \frac{3}{2} } - (2 {}^{5} ) {}^{ \frac{2}{5} } \\ \\ 6 {}^{3} - (2 {}^{5} ) {}^{ \frac{2}{5} } \\ \\ 6 {}^{3} - 2 {}^{2} \\ \\ (3 \times 2) {}^{3} -2 {}^{2} \\ \\ 3 {}^{3} \times 2 {}^{3} - 2 { }^{2} \\ \\ (3 {}^{3} \times 2 - 1) \times 2 {}^{2} \\ \\ (27 \times 2 - 1) \times 2 {}^{2} \\ \\ (27 \times 2 - 1) \times 4 \\ \\ (54 - 1) \times 4 \\ \\ 53 \times 4 \\ \\ {\red{212}}$
