Tính:
A = (37^3+12^3)/49-37*12
B = (52^3-48^3)/4+52*48
64 . 52 + 37 + 52 -3 . 25
64 . 52 + 37 . 52 - 2 . 26
64 . 52 + 37 . 52 - 2 . 26
= 64 . 52 + 37 . 52 - 52
=52 (64+37-1)
=52.100
=5200

a , 4 7 × 5 2 : 5 14 b , 3 7 × 5 2 - 5 14
Tính
a , 4 7 × 5 2 : 5 14 = b , 3 7 × 5 2 - 5 14 =
tính nhanh: 64 x 52 + 37 x 52 - 2 x 26
64 X 52 + 37 X 52 - 2 X 26
= 64 X 52 + 37 X 52 - 52
= 52 X ( 64 + 37 - 1)
= 52 X 100
= 5200
64 x 52 + 37 x 52 - 2 x 26
=64 x 52 + 37 x 52 - 52 x 1
=52 x ( 64 + 37 -1 )
=52 x 100
=5200
tk nhé
64 x 52 + 37 x 52 - 2 x 26
= 64 x 52 + 37 x 52 - 52
= ( 64 + 37 - 1 ) x 52
= 5200
Tính: 3 7 + - 5 2 + - 3 5
