Question

Tính:

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

Answer 1

\(\frac{120^3}{40^3}\)= (120:40)³ = 3³ = 27

\(\frac{390^4}{130^4}\)=(390 : 130)⁴=3⁴ = 81

\(\frac{3^2}{\left(0,375\right)^2}\)= (3:0,375)² = 8² =64

Answer 2

ai giúp mk với

mai phải nộp bài rùi

Answer 3

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

b,\(\frac{390^4}{130^4}=\frac{390}{130}=3\)

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