a) 2^10 : 2^8 = 2^(10-8) = 2^2 = 4
b) 4^6 : 4^3 = 4^(6-3) = 4^3 = 64
c) 8^5 : 8^4 = 8^(5-4) = 8^1 = 8
d) 7^4 : 7^4 = 7^(4-4) = 7^0 = 1

Cách 2 nhé :))
a) 2^10 : 2^8 = 1024 : 256 = 4
b) 4^6 : 4^3 = 4096 : 64 = 64
c) 8^5 : 8^4 = 32768 : 4096 = 8
d) 7^4 : 7^4 = 2401 : 2401 = 1

1.
Cách 1:
a) 2^10 : 2^8 = 1024 : 256 = 4
b) 4^6 : 4^3 = 4096 : 64 = 64
c) 8^5 : 8^4 = 32768 : 4096 = 8
d) 7^4 : 7^4 = 2401 : 2401 = 1

Cách 2:
a) 2^10 : 2^8 = 2^(10-8) = 2^2 = 4
b) 4^6 : 4^3 = 4^(6-3) = 4^3 = 64
c) 8^5 : 8^4 = 8^(5-4) = 8^1 = 8
d) 7^4 : 7^4 = 7^(4-4) = 7^0 = 1
