Bonjour,
Exercice 27:
a = ([tex]10^{3}[/tex])²
= [tex]10^{3*2}[/tex]
= [tex]10^{6}[/tex]
b = ([tex]10^{4}[/tex])³
= [tex]10^{4*3}[/tex]
= [tex]10^{12}[/tex]
c = [tex](10^{2}[/tex][tex])^{5}[/tex]
= [tex]10^{2*5}[/tex]
= [tex]10^{10}[/tex]
d = [tex](10^{1} )^{8}[/tex]
= [tex]10^{1*8}[/tex]
= [tex]10^{8}[/tex]
e = [tex](10^{10})^{10}[/tex]
= [tex]10^{10*10}[/tex]
= [tex]10^{100}[/tex]
f = [tex](10^{5})^{0}[/tex]
= [tex]10^{5*0}[/tex]
= [tex]10^{0}[/tex]
Exercice 28:
a = [tex](10^{-3})^{2}[/tex]
= [tex]10^{-3*2}[/tex]
= [tex]10^{-6}[/tex]
b = [tex](10^{4})^{-3}[/tex]
= [tex]10^{4*(-3)}[/tex]
= [tex]10^{-12}[/tex]
c = [tex](10^{-1})^{5}[/tex]
= [tex]10^{-1*5}[/tex]
= [tex]10^{-5}[/tex]
d = [tex](10^{-1})^{-8}[/tex]
= [tex]10^{-1*(-8)}[/tex]
= [tex]10^{8}[/tex]
e = [tex](10^{10})^{-10}[/tex]
= [tex]10^{10*(-10)}[/tex]
= [tex]10^{-100}[/tex]
f = [tex](10^{-5})^{0}[/tex]
= [tex]10^{-5*0}[/tex]
= [tex]10^{0}[/tex]
En espèrant t'avoir aidé et bon courage!
