ai giúp mik với ạ a) |-37| + (-25) × (-4) b) ¹1/2 – |-3/2| + 0.25 c) |-³7/8$ – 1 d) ¹1/2 ÷ 3/7 – |2/3| + |-2/5| × 5/5 e) (-3.7) + 6,289 f) 4.8 × 2 –

a) |-37| + (-25) × (-4)

= |-37| + 100

= 37 + 100 

= 137

b) ¹1/2 – |-3/2| + 0.25

= 3/2 – 3/2 + 1/4

= 1/4 

c) |-³7/8| – 1

= 31/8 – 1

= 23/8

d) ¹1/2 ÷ 3/7 – |2/3| + |-2/5| × 5/5

= 3/2 ÷ 3/7 – 2/3 + 2/5 x 5/5

= 7/2 – 2/3 + 2/5

= 97/30

e) (-3.7) + 6,289

= 2.589

f) 4.8 × 2 – 3.728

= 9.6 – 3.728

= 5.872

g) (-3.5) × 2 – 3,728

= -10.728

vote cho mik xin 5 sao nha
