Explications étape par étape:
LES REGLES DE BASE:
a^n*a^p=a^n+p a^n/a^p=a^n-p
a^n*b^n=(a*b)^n a^n/b^n=(a/b)^n
(a^n)^p=a^n*p
1- a)8^5*8^9=8^5+9=8^14
b)32^9/8^9=(32/8)^9=4^9
c)17^3*(17^2)^5/17^4=17^3*17^2*5/17^4
=17^3*17^10/17^4
=17^3+10/17^4
=17^13/17^4
=17^13-4
=17^9
d)7^10*(-2)^10=(7*-2)^10=-14^10
