Tính: \(T=9^9+9^{99}+9^{999}+9^{9999}+9^{99999}+9^{999999}+........+9^{9999999999}+9^{9999999999}+9^{999999999999}+9^{999999999999}\)
Rút gọn biểu thức :
(99999999+22222222222222222^2)(99999999-22222222222222222^2)
999999992-222222222222222222
A=99999999...99999999(n cs 9)
CMR : A chia hết cho 9
999999999999* 99999999999
= 2 x 1033
999999999999-?=2
999999999997
999999999999-2=999999997
chon minh nha
