a)...=(y^-8)^-3 = y^24
b)...=(a^(5-3))^2 :a^4 = (a^2)^2 : a^4=a^(4-4)=a^0=1
c)...=x^9:(x^(4-1) * x^2) = x^9:(x^(3+2))=x^9:x^5=x^(9-5)=x^4
d)...=5^(-7+3-(-2))=5^(-7+3+2)=5^-2

((5^2)^2)^2)=(5^4)^2=5^8
5^222
5^2*5^2*5^2=5^(2+2+2)=5^6
(5^22)^2=5^44
rosnąco:
5^6 , 5^8 , 5^44 , 5^222
czyli:
5^2*5^2*5^2 , ((5^2)^2)^2 , (5^22)^2 , 5^222
