☞ Formules :

• $\:{a}^{m}\times{a}^{n} = {a}^{m + n}$

• $\:{a}^{m}\times{a}^{n} \times{a}^{o}= {a}^{m + n + o}$

• $\:\dfrac{{a}^{m}}{{a}^{n}} = {a}^{m - n}$

• $\:\dfrac{{ab}^{m}}{{b}^{m}} = \dfrac{{a}^{m} \times{b}^{m}}{{b}^{m}} = {a}^{m}$

• $\:{({a}^{m})}^{n} = {a}^{m\times n}$

❑ Écrivons sous forme d'une puissance :

• $\:\boxed{\boxed{{10}^{5}\times{10}^{4} = {10}^{(5 + 4)} = {10}^{9}}}$

• $\:\boxed{\boxed{{2}^{8}\times{2}^{7} = {2}^{(8 + 7)} = {2}^{15}}}$

• $\:\boxed{\boxed{{3}^{4}\times{3}^{5}\times{3}^{2} = {3}^{(5 + 4 + 2)} = {3}^{11}}}$

• $\:\boxed{\boxed{\dfrac{{3}^{15}}{{3}^{5}} = {3}^{15 - 5} = {3}^{10}}}$

• $\:\boxed{\boxed{ \dfrac{{16}^{4}}{{5}^{4}} = \dfrac{{(3.2\times 5)}^{4}}{{5}^{4}} = \dfrac{{(3.2)}^{4} \times {5}^{4}}{{5}^{4}} = {(3.2)}^{4}}}$

• $\:\boxed{\boxed{{({4}^{3})}^{6} = {4}^{(3\times6)} = {4}^{18}}}$
