Work: Calculate the value of equation (221.4-12.2×10)×1.78+2×16.3×√1.78+12.2×10 .
Question type: Mathematical calculation
Solution:
(221.4-12.2×10)×1.78+2×16.3×√1.78+12.2×10
=99.4×1.78+2×16.3×√1.78+12.2×10
=99.4×1.78+2×16.3×1.334166+12.2×10
=176.932+2×16.3×1.334166+12.2×10
=176.932+32.6×1.334166+12.2×10
=176.932+43.493812+12.2×10
=176.932+43.493812+122
=220.425812+122
=342.425812
Answer:(221.4-12.2×10)×1.78+2×16.3×√1.78+12.2×10=342.425812
