Salut, Aidez moi SVP je ne comprend rien c'est en mathématique

Bonsoir,

Ex 6)

A - b + c - d- e+ f+ g- h+ i- j+ k- L+ m+

Ex7)

10^-3=>1/10^3=>1/1000=>0.001

10^-2=>1/10^2=>1/100=>0.01

10^-5=>1/10^5=>1/100 000=>0.000 01

10^-7=>1/10^7=>1/10 000 000=> 0.000 000 1

10^-1=>1/10^1=>1/10=>0.1

10^-6=>1/10^6=>1/1 000 000=>0.000 001

ex8)

A) 1/5^-12 = 5^12

b) 1/(-2)^-6 = (-2)^6

c) 1/3^-1 = 3^1

d) 1/(-3)^6 = (-3)^-6

e) 1/(-2)^-2 = (-2)^2

f) -1/-5^-1 = -(-5)^1

g) 1/a^-7 = a^7

h) -1/-a^-3 = -(-a)^3
