Question

17\400 . 10 elevado a 15 em notação científica

Answer 1

$\frac{17}{400} \times 10 {}^{15} = \frac{1.7 \times 10}{4 \times 10 {}^{2} } \times \frac{10 {}^{15} }{1} = \frac{1.7}{4 \times 10} \times \frac{10 {}^{15} }{1} = \\ = \frac{1.7 \times 10 {}^{1 + 15} }{4 \times 10 {}^{2} } = \frac{1.7 \times 10 {}^{16} }{4 \times 10 {}^{2} } = \frac{1.7 \times 10 {}^{16 - 2} }{4 \times 10 {}^{2 - 2} } = \frac{1.7 \times 10 {}^{14} }{4 \times 10 {}^{0} } = \\ = \frac{1.7}{4} \times 10 {}^{14} = 0.425 \times 10 {}^{14} = 4.25 \times 10 {}^{ - 1} \times 10 {}^{14} = 4.25 \times 10 {}^{( - 1) + (14)} = \\ = 4.25 \times 10 {}^{13}$
