En passant par l'écriture avec les $\times$, mettre les multiplications suivantes sous la forme $a^n$
|

|
|
\begin{eqnarray*}
|

|
|
2^3\times2^4 =& 2 \times 2 \times 2 \times 2 \times 2 \times 2 \times 2 &= 2^7\\
|

|

3^4 \times 3^5 =& \parbox{5cm}{\dotfill} & = 3^{\parbox{1cm}{\dotfill}} \\
|
||
|
|
6^2 \times 6^3 =& \parbox{5cm}{\dotfill} & = 6^{\parbox{1cm}{\dotfill}} \\
|
||
|
|
9 \times 9^6 =& \parbox{5cm}{\dotfill} & = 9^{\parbox{1cm}{\dotfill}} \\
|
||
|
|
5^4 \times 5^3 =& \parbox{5cm}{\dotfill} & = 5^{\parbox{1cm}{\dotfill}} \\
