$\displaystyle\bf\\1)\\\\16^{\frac{3}{4} } -(0,25)^{-2} =\Big(2^{4} \Big)^{\frac{3}{4} } -\Big(\frac{1}{4} \Big)^{-2} =2^{3} -4^{2} =8-16=-8\\\\1)\\\\\sqrt[5]{243p^{15} } =\sqrt[5]{(3p^{3})^{5} } =3p^{3} \\\\2)\\\\x\geq 2\\\\\sqrt[8]{(x-2)^{8} } =|x-2|=x-2\\\\3)\\\\m\leq -1\\\\\sqrt[6]{(m+1)^{6} } =|m+1|=-(m+1)\\\\4)\\\\\sqrt[4]{(3-\sqrt{10} )^{4} }=|3-\sqrt{10} |=\sqrt{10} -3$
