Question

12.10³.10⁴.10/3.10¹.10⁴

Answer 1

$\frac{12.10^{3}.10^{4}.10}{3.10^{1}.10^{4}} \ \\\\\\=\ \frac{12.10^{3+4+1}}{3.10^{1+4}} \ \\\\\\=\ \frac{12.10^{8}}{3.10^{5}} \ \\\\\\=\ \frac{12}{3} . \frac{10^{8}}{10^{5}} \\\\\\=\ 4.10^{8-5}\\\\\\\ \boxed{\boxed{4.10^{3}\ ou\ 4.1000\ \ ou\ \ 4\ 000}}\ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ ok$

Answer 2

Olá, bom dia ☺

Resolução:

$\\ \dfrac{12\cdot10^{3}\cdot10^{4}\cdot10}{3\cdot10\cdot10^{4}} \\ \\ \dfrac{12\cdot10^{8}}{3\cdot10^{5}} \\ \\ 4\cdot 10^{3} \\ \\ 4\cdot 1000 \\ \\ = 4000$

Bons estudos :)
