(1)(√2-1)的0次方+|-3|-(-(1/2))的-1次方
=1+3+1/2
=4.5
(2)0.25×(-1/2)-²-(π/3)的0次方+5
=0.25×4-1+5
=1-1+5
=5
(3)5-(-1/3)的-1次方+|-3|-(π-2)的0次方
=5+3+3-1
=10
(4)|-5|+(-(1/3))的-1次方×(π-√2)的0次方-√9+(-1)²
=5-3×13+1
=5-1+1
=5
=1+3+1/2
=4.5
(2)0.25×(-1/2)-²-(π/3)的0次方+5
=0.25×4-1+5
=1-1+5
=5
(3)5-(-1/3)的-1次方+|-3|-(π-2)的0次方
=5+3+3-1
=10
(4)|-5|+(-(1/3))的-1次方×(π-√2)的0次方-√9+(-1)²
=5-3×13+1
=5-1+1
=5
