Answer 1

$\left( \dfrac{1}{4} \right)^{ \frac{1}{2} }*16^{ \frac{1}{2} }-2^{-1}*\left( \dfrac{1}{25} \right)^{ -\frac{1}{2} }*8^{ \frac{1}{3} }= \dfrac{1}{ \sqrt{4} }* \sqrt{16}- \dfrac{1}{2}* \cfrac{1}{ \sqrt{25} } * \sqrt[3]{8} = \\ \\ = \cfrac{1}{2}*4-\cfrac{1}{2}*\cfrac{1}{5}*2=2-\cfrac{1}{5}=2-0.2=1.8$
