Answer 1

$\frac{(5b^{\frac{1}{4}} +10)(b^{\frac{3}{4}}-2b^{\frac{1}{2}})}{b-4b^{\frac{1}{2}} } =\frac{5*(b^{\frac{1}{4}}+2)*b^{\frac{1}{2}}(b^{\frac{1}{4}} -2)}{b^{\frac{1}{2}}(b^{\frac{1}{2}}-4)} =\frac{5*[(b^{\frac{1}{4}})^{2} -2^{2}]}{b^{\frac{1}{2}} -4}=\frac{5*(b^{\frac{1}{2}}-4) }{b^{\frac{1}{2}}-4 }=\boxed5$
