Work: Calculate the value of equation (20+(18-15.45)×17.3+(15.45-8)×17.9)×0.644-2×6.7×√0.644 .
Question type: Mathematical calculation
Solution:
(20+(18-15.45)×17.3+(15.45-8)×17.9)×0.644-2×6.7×√0.644
=(20+2.55×17.3+(15.45-8)×17.9)×0.644-2×6.7×√0.644
=(20+2.55×17.3+7.45×17.9)×0.644-2×6.7×√0.644
=197.47×0.644-2×6.7×√0.644
=197.47×0.644-2×6.7×0.802496
=127.17068-2×6.7×0.802496
=127.17068-13.4×0.802496
=127.17068-10.753446
=116.417234
Answer:(20+(18-15.45)×17.3+(15.45-8)×17.9)×0.644-2×6.7×√0.644=116.417234
