☆1 arithmetic calculations
[1/1 Formula]
Work: Calculate the value of equation (-sqrt3)^2+2*sqrt3*(-sqrt3)-1 .
Question type: Mathematical calculation
Solution:
(-sqrt3)^2+2*sqrt3*(-sqrt3)-1
=-1.732051^2+2*sqrt3*(-sqrt3)-1
=-1.732051^2+2*sqrt3*(-1.732051)-1
=-1.732051^2+2*1.732051*-1.732051-1
=3.000000666601+2*1.732051*(-1.732051)-1
=3.000000666601+3.464102*(-1.732051)-1
=3.000000666601+(-6.000001)-1
=-3-1
=-4
Answer:(-sqrt3)^2+2*sqrt3*(-sqrt3)-1=-4
