P/s: lớp 7 nhá!!!!!!!!!!!!!!
square root of 0: \(\sqrt{0}\)
the number of square of 0 : a có mấy giá trị để \(\sqrt{a}=\sqrt{0}\)
Cho `2x^3=3y^3=4z^3`
`CMR:(\root{3}{2x^2+3y^2+4z^2})/(\root{3}{2}+\root{3}{3}+\root{3}{4})=1`
Giúp!
Đề bài sai/thiếu
Ví dụ: \(x=y=z=0\) thì \(2x^3=3y^3=4z^3\) nhưng \(\dfrac{\sqrt[3]{2x^2+3y^2+4z^2}}{\sqrt[3]{2}+\sqrt[3]{3}+\sqrt[3]{4}}=0\)
Nếu thêm điều kiện \(\dfrac{1}{x}+\dfrac{1}{y}+\dfrac{1}{z}=1\) (với \(x;y;z\ne0\))
Đặt \(2x^3=3y^3=4z^3=k^3\Rightarrow\left\{{}\begin{matrix}x=\dfrac{k}{\sqrt[3]{2}}\\y=\dfrac{k}{\sqrt[3]{3}}\\z=\dfrac{k}{\sqrt[3]{4}}\end{matrix}\right.\)
Thay vào \(\dfrac{1}{x}+\dfrac{1}{y}+\dfrac{1}{z}=1\Rightarrow\dfrac{\sqrt[3]{2}}{k}+\dfrac{\sqrt[3]{3}}{k}+\dfrac{\sqrt[3]{4}}{k}=1\)
\(\Rightarrow\sqrt[3]{2}+\sqrt[3]{3}+\sqrt[3]{4}=k\)
Lại có:
\(\left\{{}\begin{matrix}2x^3=k^3\Rightarrow2x^2=\dfrac{k^3}{x}\\3y^3=k^3\Rightarrow3y^2=\dfrac{k^3}{y}\\4z^3=k^3\Rightarrow4z^2=\dfrac{k^3}{z}\end{matrix}\right.\) \(\Rightarrow2x^2+3y^2+4z^2=k^3\left(\dfrac{1}{x}+\dfrac{1}{y}+\dfrac{1}{z}\right)=k^3\)
\(\Rightarrow\dfrac{\sqrt[3]{2x^2+3y^2+4z^2}}{\sqrt[3]{2}+\sqrt[3]{3}+\sqrt[3]{4}}=\dfrac{\sqrt[3]{k^3}}{k}=1\)
root(2x + 2, 3) + root(2x + 1, 3) = root(2x ^ 2, 3) + root(2x ^ 2 + 1, 3)
