(5.411-3.165) : 410 = 17 nha Trần Quỳnh Mai
\(\left(5.4^{11}-3.16^5\right):4^{10}=17\)
nha bạn 
^_^
(5.411-3.165):410=(5.411-3.410):410
=5.411:410-3.410:410
=5.4-3
=17
( 5.411 - 3.165 ) : 410
= 5 . (22) 11 - 3 . ( 24) 5 : 410
= ( 5 . 222 - 3 . 220 ) : 220
= ( 5 . 22 . 220 . 3 . 220 ) : 220
= ( 20 . 220 - 3 . 220 ) : 220
= 220 ( 20 - 3 ) : 220
= 20 - 3 = 17
