Giúp mk vs mn ơi 

a) ĐKXĐ:

x³ - 1 khác 0

x khác 1

b) A = (5x² + 5x + 5)/(x³ - 1)

= 5(x² + x + 1)/[(x - 1)(x² + x + 1)]

= 5/(x - 1)

Thay x = 7 vào A, ta được:

A = 5/(7 - 1)

= 5/6

Chúc bạn hoc tốt

mình thi lâu rùi

mee,too

\(4x\sqrt[3]{\frac{1}{x}}+\frac{1}{x}.\sqrt[3]{x}=5\)

\(\Leftrightarrow4.\sqrt[3]{x^2}+\frac{1}{\sqrt[3]{x^2}}=5\)

Đặt \(\sqrt[3]{x^2}=a\)

\(\Rightarrow4a+\frac{1}{a}=5\)

\(\Leftrightarrow4a^2-5a+1=0\)

Làm tiếp đi nhé
