a)63x113+36x113+113
=113x(36+63+1)
=113x100
=11300
b)115x(36+62)-15x(62+36)
=115x98-15x98
=11270-1470
=9800
a,63.113+36.113+113
=63.113+36.113+113.1
=(63+36+1).113
=100.113
=11300
b,115.(36+62)-15.(62+36)
=115.98-15.98
=(115-15).98
=100.98
=9800
a) 63 x 113 + 36 x 113 + 113 x1
( 63 + 36 + 1 ) x 113
100 x 113 = 11300
b) 115 x ( 36 + 62 ) - 15 x ( 62 + 36 )
115 x 98 - 15 x 98
( 115 - 15 ) x 98
100 x 98 = 9800
10 115 : 36 bằng bao nhiêu ạ
