Question

Tính :

a) \(\dfrac{120^3}{40^3}\)                           b) \(\dfrac{390^4}{130^4}\)                           c) \(\dfrac{3^2}{\left(0,375\right)^2}\)

Answer 1

a,\(\dfrac{120^3}{40^3}=3\)

b,\(\dfrac{390^3}{130^3}=3\)

c,\(\dfrac{3^2}{\left(0,375\right)^2}=8\)

Answer 2

a)120³/40³= (120/40)³= 3³= 27

b)390⁴/130⁴=(390/130)⁴= 3⁴= 81

c)3²/(0,375)²= (3/0,375)²= 8²= 64

Answer 3

a) 120^3/40^3=(120/40)^3=3^3=27
b) 390^4/130^4=(390/130)^4=3^4=81

c) 3^2/(0,375)^2=(3/0.375)^2=64
