Question

Помогите пожалуйста!!!!!!

Answer 1

$displaystyle frac{x-1}{x^{3/4}+x^{1/2}}* frac{x^{1/2}+x^{1/4}}{x^{1/2}+1} *x^{1/4}+1=$

$displaystyle frac{(x^{1/2}-1)(x^{1/2}+1)*(x^{1/2}+x^{1/4})}{x^{1/4}(x^{2/4}+x^{1/4})(x^{1/2}+1)}*x^{1/4}+1=$

$displaystyle = frac{(x^{1/2}-1)}{x^{1/4}}*x^{1/4}+1= x^{1/2}-1+1=x^{1/2}$
