Bonsoir,
Exercice 1:
a.
A = [tex] \frac{4-(7-10)^5}{4+5} [/tex]
A = [tex] \frac{4-(-3)^5}{9} [/tex]
A = [tex] \frac{4-(-243)}{9} [/tex]
A = [tex] \frac{247}{9} [/tex]
A ≈ 27.44
B = [tex]( \frac{3}{2})^2- \frac{1}{3}* \frac{5}{3} [/tex]
B = [tex]( \frac{3}{2} )^2- \frac{1}{3} * \frac{5}{3} [/tex]
B = [tex] \frac{9}{4} - \frac{5}{9} [/tex]
B = [tex] \frac{81-20}{36} [/tex]
B = [tex] \frac{61}{36} [/tex]
B ≈ 1.7
b.
C = [tex] \frac{6^{-2}*3^{-2} }{2^{-2} } =9^{-2} [/tex]
C = [tex] \frac{2^2}{6^2*3^2} = \frac{1}{9^2} [/tex]
C = [tex] \frac{4}{(6*3)^2} = \frac{1}{81} [/tex]
C = [tex] \frac{4}{18^2}= \frac{1}{81} [/tex]
C = [tex] \frac{4}{324} = \frac{1}{81} [/tex]
C = [tex] \frac{1}{81} = \frac{1}{81} [/tex]
J'espère vous avoir aidé.
