考虑到 $> 0$ ， $b > 0$ , $\ sqrt {ab} = 4$ 、评估

$大概{\ frac1b \ \压裂{b}{一}}- \ frac3a \√6{\压裂{一}{b}}。$

- - - - - - \压裂{1}{4}

- - - - - - \压裂{1}{2}

\压裂{1}{2}

\压裂{1}{4}

简化 $\压裂{\ sqrt {7}} {\ sqrt {7} + \ sqrt {6}} + 7 + \ sqrt{42}。$

简化

$\压裂{1}{\ sqrt[3]{2} 1} - \压裂{\ sqrt [3] {2}} {\ sqrt [3] {4} + \ sqrt[3]{2} + 1}。$

2√[3]{2}+ 1

√[3]{4}+√[3]{2}+ 1

\ sqrt [3] {4} + 1

\ sqrt [3] {2} + 1

计算上面的表达式。

简化 $12 + \ sqrt \压裂{{17}}{12 - \ sqrt{17}} = \压裂{一}{c} + \压裂{b} {c} \ sqrt {17}$ ．

\frac{24}{127} + \frac{161}{127}根号{17}

\frac{161}{127} + frac{24}{127} \sqrt{17}

\frac{127}{161} + frac{24}{161} \sqrt{17}

\frac{24}{161} + \frac{127}{161} \sqrt{17}
