giải BPT :

a. \(\sqrt[3]{x+6}+\sqrt{x-1}\ge x^2-1\)

b.2\(\sqrt[3]{x+4}+\sqrt{2x+7}+x^2+8x+13\)

c.\(4x^3+5x^2+1\ge\sqrt{3x+1}-3x\)

giúp với ạ

giải bpt   \(\frac{2x^3+3x}{7-2x}\ge\sqrt{2-x}\)

giải bpt

\(\left(\sqrt{x+4}-1\right)\sqrt{x+2}\ge\frac{x^3+4x^2+3x-2\left(x+3\right)\sqrt[3]{2x+3}}{\left(\sqrt[3]{2x+3}-3\right)\left(\sqrt{x+4}+1\right)}\)

1. Giải bpt: \(\sqrt{x-2}-2\ge\sqrt{2x-5}-\sqrt{x+1}\)

2. Với \(x\in\left(0;1\right)\) tìm Min \(P=\dfrac{\sqrt{1-x}\left(1+\sqrt{1-x}\right)}{x}+\dfrac{5}{\sqrt{1-x}}\)

giải bpt:

1. \(\frac{\sqrt{-3x^2+x+4}+2}{x}< 2\)

2. \(\sqrt{x^2-3x+2}+\sqrt{x^2-4x+3}\ge2\sqrt{x^2-5x+4}\)

3. \(\sqrt{x^2-8x+15}+\sqrt{x^2+2x-15}\le\sqrt{4x^2-18x=18}\)

4. 4(x+1)² \(\ge\) (2x +10)( 1- \(\sqrt{3+2x}\))²

5. \(\sqrt{1+x}-\sqrt{1-x}\ge x\)

giải bpt sau : \(\sqrt{x^2-3x+20}+\sqrt{x^2-4x+3}\ge\sqrt{x^2-5x+4}\)

Giải bpt

\(\frac{x+2}{\sqrt{2x+3}-\sqrt{x+1}}\ge\sqrt{2x^2+5x+3}+1\)

Giải BPT  \(\sqrt{x^2+2x-3}-2\ge\sqrt{x+3}+\sqrt{x-1}\)

Giai bpt :
