235*(30+5)
=
235 x (30 + 5 ) =
235x(30+5)=235x35=8225
****nha các bạn
235 x ( 30 + 5 ) = 235 x 35 = 8225
235 x (30 + 5 )
= 235 x 35
= 8225 .
Tick mk nha ! Nguyễn Linh Đan
Tính:
a) (-30) + (-5)
b) (-7 ) + (-13)
c) (-15) + (-235)
a) (–30) + (–5) = –(30 + 5) = –35.
b) (–7) + (–13) = – (7 + 13) = –20;
c) (–15) + (–235) = –(15 + 235) = –250.
235×46+30÷765-235×16
235 × 46 + 30 ÷ 765 - 235 × 16
= 10810 + 2/51 - 3760
= 359552/51
= 10810 + \(\dfrac{2}{51}\) - 3760
= \(\dfrac{359552}{51}\)
