Answer 1

Explicação passo-a-passo:

1)

a)

-> $[(-3)^{4} ]^{3}$

-> $(-3)^{12}$

-> $3^{12}$

b)

-> $[(\frac{2}{5} )^{-1} ]^{-2}$

-> $(\frac{2}{5} )^{2}$

-> $\frac{4}{25}$

c)

-> $[(3^{4} )^{4} ]^{4}$

-> $(3^{4} )^{16}$

-> $3^{64}$

2)

-> $\frac{3^{2^{3} }-5^{4} }{4^{4}+ 20^{3} }$

-> $\frac{3^{8} - 625}{256 + 8000}$

-> $\frac{6561-625}{8256}$

-> $\frac{5936}{8256}$ ≅ $0,72$

3)

-> $\frac{2^{98}+ 4^{50} - 8^{34} }{2^{99} -32^{20} + 2^{101} }$

-> $\frac{2^{98}+ 2^{100} - 2^{102} }{2^{99}- 2^{100} + 2^{101} }$

-> $\frac{(2^{98})(1+ 2^{2} - 2^{4}) }{(2^{98})(2- 2^{2} +2^{3} ) }$

-> $\frac{1 + 4 -16}{2-4+8}$

-> $\frac{-11}{6}$
