rut gon phan so 2^10.3^10-2^10.3^9 /2^9.3^10
Phân số trên = 2^10.3^9.(3-1)/2^9.3^10
= 2^10.3^9.2/2^9.3^10
= 2^11.3^9/2^9.3^10
= 2^2/3 = 4/3

a ) Tử số : 2^10 . 3^10 - 2^10 . 3^9
= 2^10 . 3^9 ( 3 - 1 )
= 2^10 . 3^9 . 2 = 2^11 . 3^9
=> Phân số : 2^11 . 3^9 /2^9 . 3^10 = 4/3
b ) 5^12 . 7^12 + 9 . 5^11 . 7^11
= 5^11 . 7^11 ( 5 . 7 + 9 )
=5^11 . 7^11 . 44
