Witam bardzo prosze o pomoc ;) Oblicz potęgi: a) [(-1)^2]^3= (1^3)^15= [(-1)^7]^4= b) [(-0,1)^2]^3= (0,2^3)^2= [-(-0,1)^2]^3= c) (-3a^2b)^3= (-ab^2cd^2)^5= [(1/2ab)^3 * (2ab^2)^2]^3= Bardzo proszę o rozpisanie tych zadań,żebym wiedziala o co chodzi ;)

A) [(-1)^2]^3=[1]^3=1 (1^3)^15=1^15=1 [(-1)^7]^4=[1]^4=1 b) [(-0,1)^2]^3=[0,01]^3=0,000001 (0,2^3)^2=0,008^2=0,000064 [-(-0,1)^2]^3=[-0,01]^3=(-0,000001) c) (-3a^2b)^3=(-27a^8b) (-ab^2cd^2)^5=-ab^10cd^10 [(1/2ab)^3*(2ab^2)^2]^3=[1/8ab^3*4ab^4]^3=1/512ab^27*64^12
(1^3)^15=1^15=1
[(-1)^7]^4=[1]^4=1
b) [(-0,1)^2]^3=[0,01]^3=0,000001
(0,2^3)^2=0,008^2=0,000064
[-(-0,1)^2]^3=[-0,01]^3=(-0,000001)
c) (-3a^2b)^3=(-27a^8b)
(-ab^2cd^2)^5=-ab^10cd^10
[(1/2ab)^3*(2ab^2)^2]^3=[1/8ab^3*4ab^4]^3=1/512ab^27*64^12
