Question

C) radical0,0225-0,(6)×radical1,125×2+radical0,04

Answer 1

$\sqrt{0.0225}=\sqrt{ \frac{225}{10000} }=\sqrt{\frac{15^{2} }{10^{4} } } =\frac{15}{100}=\frac{3}{20}$$0,(6)=\frac{6}{9} =\frac{2}{3}$

$\sqrt{1.125} =\sqrt{\frac{1125}{1000} } =\frac{35}{10\sqrt{10} } *2$

$\sqrt{0.04} =\sqrt{\frac{4}{100} } =2/10=1/5$
