Question type: Mathematical calculation
Solution:
(256.84-9.7×10)×0.311-2×4.7×√0.311+9.7×10
=159.84×0.311-2×4.7×√0.311+9.7×10
=159.84×0.311-2×4.7×0.557674+9.7×10
=49.71024-2×4.7×0.557674+9.7×10
=49.71024-9.4×0.557674+9.7×10
=49.71024-5.242136+9.7×10
=49.71024-5.242136+97
=44.468104+97
=141.468104
Answer:(256.84-9.7×10)×0.311-2×4.7×√0.311+9.7×10=141.468104
