Zad.5/22 str
Zapisz w postaci jednej potęgi i oblicz:
a) 2^7 * 5^7 =
b) (1/2)^3 * 4^5 =
c) 16^10 : 8^10 =
d) (3/5)^4 :(1/5)^4 =
e) 0,2^3 * 10^3 =
f) (-1/3)^3 :(1/9)^3 =
g) (-0,2)^9 : 0,1^9 =
h) (4/3)^3 * (3/4)^3 =
Za obliczenie i wyniki daję naj :)
bardzo prosze o odpowiedź :)

b) (1/2)^3 * 4^5 =2^(-3)*(2^2)^5 = 2^(-3) * 2^10 = 2^7 = 128
c) 16^10 : 8^10 =(16:8)^10 = 2^10 = 1024
d) (3/5)^4:(1/5)^4 =(3/5 : 1/5)^4 = (3/5 * 5/1) ^4 = 3^4 = 81
e) 0,2^3 * 10^3 = (0,2*10)^3 = 2^3 = 8
f) (-1/3)^3 :(1/9)^3 =(-1/3:1/9)^3 = (-1/3 * 9/1) ^3 = (-3) ^ 3 = -27
g) (-0,2)^9 : 0,1^9 = (-0,2 : 0,1) ^9 = (-2:1) ^ 9 = (-2)^9 = -512
h) (4/3)^3 * (3/4)^3 =(4/3 * 3/4) ^3 = 1^3 = 1
