Work: Calculate the value of equation (75.6-4.2×10)×1.42+2×10×√1.42+-4.2×10 .
Question type: Mathematical calculation
Solution:
(75.6-4.2×10)×1.42+2×10×√1.42+-4.2×10
=33.6×1.42+2×10×√1.42+-4.2×10
=33.6×1.42+2×10×1.191638+-4.2×10
=47.712+2×10×1.191638+(-4.2)×10
=47.712+20×1.191638+(-4.2)×10
=47.712+23.83276+(-4.2)×10
=47.712+23.83276+(-42)
=71.54476+(-42)
=29.54476
Answer:(75.6-4.2×10)×1.42+2×10×√1.42+-4.2×10=29.54476
