За решение двух задании отмечу как лучшее
[tex]1. ( \sqrt{( \sqrt{2} -1,5)^{2} } - \sqrt[3]{(1- \sqrt{2})^3} )^2+0,75[/tex]
[tex] 2. ( \frac{2+x^{ \frac{1}{4}}}{2-x^{ \frac{1}{4}}} - \frac{{2-x^{ \frac{1}{4}}}}{2+x^{ \frac{1}{4}}} ) * \frac{4- \sqrt{x} }{ \sqrt[4]{x^3}}[/tex]

1.---
( √(√2- 1,5)² -∛(1 -√2)³ )² +0,75 =(1,5 -√2 -(1-√2) )² +0,75 =0,5² +0,75 =1.
* * * ! √ (√2- 1,5)² = |√2- 1,5| = -(√2- 1,5) =1,5 - √2. * * *
2.

( (2+ x^1/4 )/(2 -x^1/4) - (2- x^1/4 )/(2+x^1/4) ) * (4 -√ x ) / x^ 3/4 =
( (2+ x^1/4 )² - (2- x^1/4 )² ) )/( 4 - √ x) * (4 -√ x ) / x^ 3/4 =
=8*x^1/4 / x^3/4 =8 / x^(-1/2) =8 / √x * * * 8√x / x * * *
