Question

5.10^8 x 4.10^-3 ?? Porque da 2.10^6 ?? Por favor passo a passo

Answer 1

$5 \times {10}^{8} \times 4 \times {10}^{ - 3} = 2 \times {10}^{6} \\ \\ 5 \times {10}^{8} \times \frac{1}{4 \times {10}^{3} } = 2 \times {10}^{6} \\ \\ \frac{5 \times {10}^{5} }{4} = 2 \times {10}^{6} \\ \\ \frac{0.5 \times {10}^{6} }{4} = 2 \times {10}^{6} \\ \\ \frac{ \frac{1}{2} \times {10}^{6} }{4} = 2 \times {10}^{6} \\ \\ \frac{1}{2} \times \frac{4}{1} \times {10}^{6} = 2 \times {10}^{6} \\ \\ 2 \times {10}^{6} = 2 \times {10}^{6}$
