Bonsoir,
A = 2 x 2 x 2 x 2 = 16
B = (-3) x (-3) = 9
C = 1 x 1 x 1 x 1 x 1 x ......... x 1 x 1 = 1
D = 0.1 x 0.1 x 0.1 = 0.001
[tex]E = 7 ^{3+4} = 7^{7}[/tex]
[tex]B = 3 ^{-7*8} = 3 ^{56} [/tex]
[tex]C = \frac{1 ^{7} }{8 ^{7} } = \frac{1}{8^{7} } [/tex]
[tex]D = (\frac{12}{4}) ^{5} [/tex]
[tex]A = 1.245.10^{1} [/tex]
[tex]B = 5.10^{-3} [/tex]
[tex]C = 3.10 ^{-5} [/tex]
Bonne soirée !
