Work: Calculate the value of equation (20+(18-15.45)×17.3+(15.45-8)×17.9+(8-6)×19.3)×0.65-2×20.7×√0.65 .
Question type: Mathematical calculation
Solution:
(20+(18-15.45)×17.3+(15.45-8)×17.9+(8-6)×19.3)×0.65-2×20.7×√0.65
=(20+2.55×17.3+(15.45-8)×17.9+(8-6)×19.3)×0.65-2×20.7×√0.65
=(20+2.55×17.3+7.45×17.9+(8-6)×19.3)×0.65-2×20.7×√0.65
=(20+2.55×17.3+7.45×17.9+2×19.3)×0.65-2×20.7×√0.65
=236.07×0.65-2×20.7×√0.65
=236.07×0.65-2×20.7×0.806226
=153.4455-2×20.7×0.806226
=153.4455-41.4×0.806226
=153.4455-33.377756
=120.067744
Answer:(20+(18-15.45)×17.3+(15.45-8)×17.9+(8-6)×19.3)×0.65-2×20.7×√0.65=120.067744
