Work: Calculate the value of equation (20+(18-15.45)×17.3)×0.81-2×5×√0.81 .
Question type: Mathematical calculation
Solution:
(20+(18-15.45)×17.3)×0.81-2×5×√0.81
=(20+2.55×17.3)×0.81-2×5×√0.81
=64.115×0.81-2×5×√0.81
=64.115×0.81-2×5×0.9
=51.93315-2×5×0.9
=51.93315-10×0.9
=51.93315-9
=42.93315
Answer:(20+(18-15.45)×17.3)×0.81-2×5×√0.81=42.93315
