Answer 1

$1)\sqrt{15+\sqrt{29} }=\sqrt{\frac{29}{2} +\sqrt{29} +\frac{1}{2} }=\sqrt{\Big(\sqrt{\frac{29}{2} }+\sqrt{\frac{1}{2} }\Big)^{2} }=\boxed{\sqrt{14,5}+\sqrt{0,5}}$

$2)\sqrt{a+b-2\sqrt{ab} }=\sqrt{(\sqrt{a})^{2} -2\sqrt{ab}+(\sqrt{b})^{2}}=\sqrt{(\sqrt{a}-\sqrt{b})^{2}} =\boxed{\Big|\sqrt{a}-\sqrt{b}\Big|}$
