Question

Пожалуйста, упростите выражение

Answer 1

$1)3/( x^{1/4} +y ^{1/4} )+3/( ^{1/4} -y ^{1/4} )=3(x ^{1/4} -y ^{1/4} +x ^{1/4} +y ^{1/4})/( x^{1/2} -$$y ^{1/2} )=6x ^{1/4} /( x^{1/2} -y ^{1/2} )$
$2)1/y ^{1/2} -1/ x^{1/2} )=(x ^{1/2} -y ^{1/2} )/(xy) ^{1/2}$
$3)(x ^{1/2} -y ^{1/2} )/(xy) ^{1/2} *x ^{1/4}y ^{1/2}=( x^{1/2} -y ^{1/2} /4x ^{1/4}$
$4)6x ^{1/4}/( x^{1/2} -y ^{1/2})*(x ^{1/2} -y ^{1/2} )/4x ^{1/4} =6/4=1,5$
