cam on cac ban nhieu
(5^4-5^3)^3/125^4-64/125
(5^4-5^3/125^4)=64/125
Thực hiện phép tính :(3+3:12+3:47+3:53+3:127+3:150):(13:12-46:47+54:53-126:127+151:150)
(x + 5)3 = \(\dfrac{-64}{125}\)
Vì sao : (5^4×5^3)^3/125^4=64/125
Mong các bạn giúp mình ạ :<
\(\frac{\left(5^4-5^3\right)}{125^4}-\frac{64}{125}\)
Chứng minh : \(\frac{\left(5^4-5^3\right)^3}{125^4}=\frac{64}{125}\)
(3/5-2/3.x)3=-64/125
