[1/1 Formula]
Work: Calculate the value of equation (0.2-0.1)^2×0.3+(0.1-0.1)^2×0.5+(-0.05-0.1)^2×0.2 .
Question type: Mathematical calculation
Solution:
(0.2-0.1)^2×0.3+(0.1-0.1)^2×0.5+(-0.05-0.1)^2×0.2
=0.1^2×0.3+(0.1-0.1)^2×0.5+(-0.05-0.1)^2×0.2
=0.1^2×0.3+0^2×0.5+(-0.05-0.1)^2×0.2
=0.1^2×0.3+0^2×0.5+(-0.15)^2×0.2
=0.01×0.3+0^2×0.5+(-0.15)^2×0.2
=0.01×0.3+0×0.5+(-0.15)^2×0.2
=0.01×0.3+0×0.5+0.0225×0.2
=0.003+0×0.5+0.0225×0.2
=0.003+0+0.0225×0.2
=0.003+0+0.0045
=0.003+0.0045
=0.0075
Answer:(0.2-0.1)^2×0.3+(0.1-0.1)^2×0.5+(-0.05-0.1)^2×0.2=0.0075
