Chào bạn ! Sau đây là lời giải chi tiết và cơ bản nhất bạn nhé :
A/ 100 + ( - 52 ) + 114 + ( - 62 )
= 48 + 52
= 100
B)125 × (-61) × (-2)^3 × (-1)^2016
= 125 . ( - 61 ) x ( -8 ) x 1
= ( - 7625 ) x -8
= - 61000
C) (-37) + 54 + (-70) + (-163) + 246
= ( - 37 ) + ( - 163 ) + 54 + 246 + ( - 70 )
= ( - 200 ) + 300 + ( - 70 )
= 100 + ( - 70 )
= 30
D) 28 × 76 - 18 × 28 + 9 × 28
= 28 x ( 76 - 18 + 9 )
= 28 x 67
= 1876
E)217 + [43 + (-217) + (-23)]
= 217 + [ 43 + ( - 240 ) ]
= 217 + ( - 197 )
= 20
F) 369 - 4 × { (- 5 ) + 4 × (-8) }
= 369 - 4 x { ( - 5 ) + ( - 32 ) }
= 369 - 4 x ( - 37 )
= 369 - ( - 148 )
= 369 + 148
= 517

125*98-125*46-52*25
Giúp mình nha
48 × 19 + 48 × 115 + 134 × 52
= 48 × ( 19 + 115 ) + 134 × 52
= 48 × 134 + 134 × 52
= 134 × ( 48 + 52 )
= 134 × 100
= 13400
48 * 19 + 48 * 115 + 134 * 52
= 48 * ( 19 + 115 ) + 134 * 52
=48* 134 + 134 * 52
= 134 * ( 48 + 52 )
= 134 x 100
= 13 400
^^ Học tốt nha!
Mấy câu sau cứ lm tương tự zậy! :v
48 x 19 + 48 x 115 + 134 x 52
= 48 x ( 19 + 115 ) + 134 x 52
= 48 x 134 + 134 x 52
= 134 x ( 48 + 52 )
= 134 x 100
= 134 00

Tính:

B = (52^3-48^3)/4+52*48
62 - 52 + 37+ 28 - 38 + 63
62 - 52 + 37 + 28 - 38 + 63
= ( 62 - 52 ) + ( 37 + 63 ) + ( 28 - 38 )
= 10 + 100 + - 10
= 110 + - 10
= 100
\(62-52+37+28-38+63\)
= \(\left(62+28\right)-\left(52+38\right)+\left(37+63\right)\)
= \(90-90+100\)
= \(100\)
62 - 52 + 37 + 28 - 38 + 63
= (62 - 52) - (38 - 28) + (37 + 63)
= 10 - 10 + 100
= 0 + 100
= 100
