Odpowiedź:
16 x 16 = 256
256 : 16 = 16
2 x 2 x 2 x 2 = 16
ODP 4
Szczegółowe wyjaśnienie:
1.
a^?* 16 = 2^8
a^? * 2^4 = 2^8
a^4 * 2^4 = 2^8
2.
4^5 : 4² = 4³
3.
(4ab²)³ = 64a³b^6
odp. ostatnia
4.
125^6 = (5³)^6 = 6^18
5.
(4 1/2)³ * (-2/3)³ = (-9/2 * 2/3)³ = (-3)³ = -27
0,8^4 : (2 2/3)^4 = (4/5 : 8/3)^4 = (4/5 * 3/8)^4 = (3/10)^4 = 0,0003
(1 3/4)^6 * (2/7)^6 = (7/4 * 2/7)^6 = (1/2)^6
