Answer 1

$\large\boxed{\begin{array}{l}\rm\bigg[\sqrt{0,25}+4\cdot(0,5)^4+(8)^{-\frac{2}{3}}\bigg]+2^0\\\rm\bigg[0,5+4\cdot 0,0625+(2^3)^{-\frac{2}{3}}\bigg]+1\\\\\rm\bigg[0,5+0,25+2^{-2}\bigg]+1\\\rm\bigg[0,5+0,25+\dfrac{1}{4}\bigg]+1\\\\\rm \bigg[\dfrac{2}{4}+\dfrac{1}{4}+\dfrac{1}{4}\bigg]+\dfrac{4}{4}\\\\\rm\dfrac{4}{4}+\dfrac{4}{4}=\dfrac{8}{4}=2\end{array}}$

$\Large\boxed{\begin{array}{l}\rm\bigg[\sqrt{0,25}+4\cdot (0,5)^4+(8)^{-\frac{2}{3}}\bigg]+2^0=2\end{array}}$
