Work: Calculate the value of equation 7.54×(2.4)×0.854-2×9×√0.854-2×10.5×√0.87 .
Question type: Mathematical calculation
Solution:
7.54×(2.4)×0.854-2×9×√0.854-2×10.5×√0.87
=7.54×2.4×0.854-2×9×√0.854-2×10.5×√0.87
=7.54×2.4×0.854-2×9×0.924121-2×10.5×√0.87
=7.54×2.4×0.854-2×9×0.924121-2×10.5×0.932738
=18.096×0.854-2×9×0.924121-2×10.5×0.932738
=15.453984-2×9×0.924121-2×10.5×0.932738
=15.453984-18×0.924121-2×10.5×0.932738
=15.453984-16.634178-2×10.5×0.932738
=15.453984-16.634178-21×0.932738
=15.453984-16.634178-19.587498
=-1.180194-19.587498
=-20.767692
Answer:7.54×(2.4)×0.854-2×9×√0.854-2×10.5×√0.87=-20.767692
