Answer 1

boa noite !!!!

$1) \\ \\ \frac{64 \times 10 {}^{31} \times 2 \times 10 {}^{ - 20} }{8 \times 10 {}^{9} } \\ \\ 8 \times 10 {}^{22} \times 2 \times 10 {}^{ - 20} \\ \\ 2 {}^{3} \times 2 {}^{22} \times 5 {}^{22} \times 2 \times 5 {}^{ - 20} \\ \\ 2 {}^{6} \times 5 {}^{2} \\ \\ 67 \times 25 \\ \\ = 1600 \\ \\ \\ 2) \\ \\ \frac{(2 {}^{3} ) {}^{6} \times (2 {}^{5} ) {}^{2} }{(2 {}^{15}) {}^{2} }{} \\ \\ \frac{2 {}^{18} \times 2 {}^{10} }{2 {}^{30} } \\ \\ \frac{2 {}^{28} }{2 {}^{30} } \\ \\ \frac{1}{2 {}^{2} } \\ \\ \frac{1}{4} \\ \\ = 2 {}^{ - 2} \\ \\ \\ 3) \\ \\ 778 = 7,78 \times 10 {}^{2} \\ 0,0000000000000000016 = 1,6 \times 10 {}^{ - 18} \\ \\ \\ 4) \\ \\ ( \frac{ - 1}{3} ) {}^{ - 2} + ( \frac{1}{2} ) {}^{ - 3} \\ \\ ( \frac{3}{ - 1} ) {}^{2} + 2 {}^{3} \\ \\ ( - 3) {}^{2} + 8 \\ \\ 9 + 8 \\ \\ = 17$

espero que eu tenha conseguido te ajudar....
