Oblicz:
a)
(-1\frac{1}{2})^2*\sqrt{0,04}+2^0:0,75
b)
(\sqrt2-1)^0-(\frac{1}{2})^{-2}

(-1\frac{1}{2})^2*\sqrt{0,04}+2^0:0,75=(-\frac{3}{2})^2*0,2+1:\frac{3}{4}=
=\frac{9}{4}*\frac{2}{10}+1*\frac{4}{3}=\frac{9}{20}+\frac{4}{3}=\frac{27}{60}+\frac{80}{60}=\frac{107}{60}=1\frac{47}{60}
(\sqrt2-1)^0-(\frac{1}{2})^{-2}=1-2^2=1-4=-3
