Bonjour,
[tex]A = 10 {}^{2} \times 10 {}^{5} = 10 {}^{2 + 5} = \green{10 {}^{7} }[/tex]
[tex]B = \frac{10 {}^{7} }{10 {}^{2} } = 10 {}^{7 - 2} = \green{ {10}^{5} }[/tex]
[tex]C = {10}^{4} \times {10}^{ - 3} = 10 {}^{4 - 3} =10 {}^{1} =\green{ {10}^{} }[/tex]
[tex]D = {3}^{4} \times {3}^{3} = 3 {}^{4 + 3} = \green{3 {}^{7} }[/tex]
[tex]E = ( - 2) {}^{3} \times ( - 2) {}^{2} = ( - 2) {}^{3 + 2} = \green{( - 2) {}^{5} }[/tex]
[tex]F = \frac{2 {}^{8} }{2 {}^{3} } = 2 {}^{8 - 3} =\green{ {2}^{5} }[/tex]
