$a) \: \: 4 {}^{ - 2} \\ \\ \frac{1}{4 {}^{2} } \\ \\ \frac{1}{16}$

$b) \: \: 0.1 {}^{5} \\ \\ ( \frac{1}{10} ) {}^{ 5} \\ \\ \frac{1 {}^{5} }{10 {}^{5} } \\ \\ \frac{1}{10 {}^{5} } \\ \\ \frac{1}{100000}$

$c) \: \: ( \frac{1}{100} ) {}^{3} \\ \\ \frac{1 {}^{3} }{100 {}^{3} } \\ \\ \frac{1}{100 {}^{3} }$

$d) \: \: ( \frac{1}{1000000} ) {}^{0} \\ \\ 1$

$e) \: \: 2 {}^{3} \\ \\ 2 \times 2 \times 2 \\ \\ 8$

$f) \: \: (2.5) {}^{3} \\ \\ ( \frac{5}{2} ) {}^{3} \\ \\ \frac{5 {}^{3} }{2 {}^{3} } \\ \\ \frac{125}{2 {}^{3} } \\ \\ \frac{125}{8}$

$g) \: \: ( \frac{1}{4} ) {}^{ - 2} \\ \\ 4 {}^{2} \\ \\ 4 \times 4 \\ \\ 16$

4-

$\frac{81}{243} \\ \\ \frac{81 \div 81}{243 \div 81} \\ \\ \frac{1}{243 \div 81} \\ \\ \frac{1}{3} \\ \\ 3 {}^{ - 1}$

5-

$a) \: \: 3 \times (4) {}^{2} + 4 \times (3) {}^{2} \\ \\ 4 \times 3(4 + 3) \\ \\ 4 \times 3 \times 7 \\ \\ 12 \times 7 \\ \\ 84$

$b) \: \: 200 {}^{ - 2} \times 100 + 100 {}^{ - 1} \times 100 \\ \\ 200 {}^{ - 2} \times 100 + 10 {}^{ - 2} \times 200 \\ \\ (20 {}^{ - 2} \times 100 + 200) \times 10 {}^{ - 2} \\ \\ ( \frac{1}{20 {}^{2} } \times 100 + 200) \times 10 {}^{ - 2} \\ \\ ( \frac{1}{20 {}^{2} } \times 100 + 200) \times \frac{1}{10 {}^{2} } \\ \\ ( \frac{100}{20 {}^{2} } + 200) \times \frac{1}{10 {}^{2} } \\ \\ ( \frac{100}{20 {}^{2} } + 200) \times \frac{1}{100} \\ \\ ( \frac{100}{400} + 200) \times \frac{1}{100} \\ \\ \frac{801}{4} \times \frac{1}{100} \\ \\ \frac{801}{400}$

$c) \: \: ( \frac{3}{5} ) {}^{ - 2} \times ( \frac{5}{2} ) {}^{ - 3} - ( \frac{4}{3} ) {}^{ - 2} \times ( \frac{1}{4} ) {}^{ - 2} \\ \\ ( \frac{5}{3} ) {}^{2} \times ( \frac{5}{2} ) {}^{ - 3} - ( \frac{4}{3} ) {}^{ - 2} \times ( \frac{1}{4} ) {}^{ - 2} \\ \\ ( \frac{5}{3} ) {}^{2} \times ( \frac{2}{5} ) {}^{3} - (\frac{4}{3} ) {}^{ - 2} \times ( \frac{1}{4} ) {}^{ - 2} \\ \\ ( \frac{5}{3} ) {}^{2} \times ( \frac{2}{5} ) {}^{3} - ( \frac{4}{3} \times \frac{1}{4} ) {}^{ - 2} \\ \\ \frac{25}{9} \times ( \frac{2}{5} ) {}^{3} - ( \frac{1}{3} ) {}^{ - 2} \\ \\ \frac{25}{9} \times \frac{8}{125} - ( \frac{1}{3} ) {}^{ - 2} \\ \\ \frac{1}{9} \times \frac{8}{5} - ( \frac{1}{3} ) {}^{ - 2} \\ \\ \frac{1}{9} \times \frac{8}{5} - 3 {}^{2} \\ \\ \frac{8}{45} - 3 {}^{2} \\ \\ \frac{8}{45} - 9 \\ \\ - \frac{397}{45}$
