Answer 2

Resposta:

a. 12615

b. 44082

Explicação passo a passo:

a. $435\cdot \:29$

$\begin{matrix}\space\space&4&3&5\\ \times \:&\space\space&2&9\end{matrix}$

$\frac{\begin{matrix}\space\space&\space\space&4&\space\space\\ \space\space&4&3&\textbf{5}\\ \times \:&\space\space&2&\textbf{9}\end{matrix}}{\begin{matrix}\space\space&\space\space&\space\space&5\end{matrix}}$

$\frac{\begin{matrix}\space\space&3&\textbf{4}&\space\space\\ \space\space&4&\textbf{3}&5\\ \times \:&\space\space&2&\textbf{9}\end{matrix}}{\begin{matrix}\space\space&\space\space&1&5\end{matrix}}$

$\frac{\begin{matrix}\space\space&3&\textbf{3}&4&\space\space\\ \space\space&\space\space&\textbf{4}&3&5\\ \times \:&\space\space&\space\space&2&\textbf{9}\end{matrix}}{\begin{matrix}\space\space&\space\space&9&1&5\end{matrix}}$

$\frac{\begin{matrix}\space\space&3&3&4&\space\space\\ \space\space&\space\space&4&3&5\\ \times \:&\space\space&\space\space&2&9\end{matrix}}{\begin{matrix}\space\space&3&9&1&5\end{matrix}}$

$\frac{\begin{matrix}\space\space&\space\space&\space\space&1&\space\space\\ \space\space&\space\space&4&3&\textbf{5}\\ \space\space&\times \:&\space\space&\textbf{2}&9\end{matrix}}{\begin{matrix}\space\space&3&9&1&5\\ \space\space&\space\space&\space\space&0&\space\space\end{matrix}}$

$\frac{\begin{matrix}\space\space&\space\space&\space\space&\textbf{1}&\space\space\\ \space\space&\space\space&4&\textbf{3}&5\\ \space\space&\times \:&\space\space&\textbf{2}&9\end{matrix}}{\begin{matrix}\space\space&3&9&1&5\\ \space\space&\space\space&7&0&\space\space\end{matrix}}$

$\frac{\begin{matrix}\space\space&\space\space&\space\space&1&\space\space\\ \space\space&\space\space&\textbf{4}&3&5\\ \space\space&\times \:&\space\space&\textbf{2}&9\end{matrix}}{\begin{matrix}\space\space&3&9&1&5\\ \space\space&8&7&0&\space\space\end{matrix}}$

$\frac{\begin{matrix}\space\space&\space\space&4&3&5\\ \space\space&\times \:&\space\space&2&9\end{matrix}}{\begin{matrix}\space\space&3&9&1&5\\ \space\space&8&7&0&0\end{matrix}}$

$3915+8700=12615$

b. $711\cdot \:62$

$\begin{matrix}\space\space&7&1&1\\ \times \:&\space\space&6&2\end{matrix}$

$\frac{\begin{matrix}\space\space&7&1&\textbf{1}\\ \times \:&\space\space&6&\textbf{2}\end{matrix}}{\begin{matrix}\space\space&\space\space&\space\space&2\end{matrix}}$

$\frac{\begin{matrix}\space\space&7&\textbf{1}&1\\ \times \:&\space\space&6&\textbf{2}\end{matrix}}{\begin{matrix}\space\space&\space\space&2&2\end{matrix}}$

$\frac{\begin{matrix}\space\space&1&\space\space&\space\space&\space\space\\ \space\space&\space\space&\textbf{7}&1&1\\ \times \:&\space\space&\space\space&6&\textbf{2}\end{matrix}}{\begin{matrix}\space\space&\space\space&4&2&2\end{matrix}}$

$\frac{\begin{matrix}\space\space&1&\space\space&\space\space&\space\space\\ \space\space&\space\space&7&1&1\\ \times \:&\space\space&\space\space&6&2\end{matrix}}{\begin{matrix}\space\space&1&4&2&2\end{matrix}}$

$\frac{\begin{matrix}\space\space&\space\space&7&1&\textbf{1}\\ \space\space&\times \:&\space\space&\textbf{6}&2\end{matrix}}{\begin{matrix}\space\space&1&4&2&2\\ \space\space&\space\space&\space\space&6&\space\space\end{matrix}}$

$\frac{\begin{matrix}\space\space&\space\space&7&\textbf{1}&1\\ \space\space&\times \:&\space\space&\textbf{6}&2\end{matrix}}{\begin{matrix}\space\space&1&4&2&2\\ \space\space&\space\space&6&6&\space\space\end{matrix}}$

$\frac{\begin{matrix}\space\space&4&\space\space&\space\space&\space\space\\ \space\space&\space\space&\textbf{7}&1&1\\ \times \:&\space\space&\space\space&\textbf{6}&2\end{matrix}}{\begin{matrix}\space\space&1&4&2&2\\ \space\space&2&6&6&\space\space\end{matrix}}$

$\frac{\begin{matrix}\space\space&4&\space\space&\space\space&\space\space\\ \space\space&\space\space&7&1&1\\ \times \:&\space\space&\space\space&6&2\end{matrix}}{\begin{matrix}\space\space&1&4&2&2\\ 4&2&6&6&\space\space\end{matrix}}$

$\frac{\begin{matrix}\space\space&\space\space&7&1&1\\ \space\space&\times \:&\space\space&6&2\end{matrix}}{\begin{matrix}0&1&4&2&2\\ 4&2&6&6&0\end{matrix}}$

$1422+42660=44082$
