Work: Calculate the value of equation 120*1.5^5-820*1.5^4+2060*1.5^3-2340*1.5^2+1180*1.5-200 .
Question type: Mathematical calculation
Solution:
120*1.5^5-820*1.5^4+2060*1.5^3-2340*1.5^2+1180*1.5-200
=120*7.59375-820*1.5^4+2060*1.5^3-2340*1.5^2+1180*1.5-200
=120*7.59375-820*5.0625+2060*1.5^3-2340*1.5^2+1180*1.5-200
=120*7.59375-820*5.0625+2060*3.375-2340*1.5^2+1180*1.5-200
=120*7.59375-820*5.0625+2060*3.375-2340*2.25+1180*1.5-200
=911.25-820*5.0625+2060*3.375-2340*2.25+1180*1.5-200
=911.25-4151.25+2060*3.375-2340*2.25+1180*1.5-200
=911.25-4151.25+6952.5-2340*2.25+1180*1.5-200
=911.25-4151.25+6952.5-5265+1180*1.5-200
=911.25-4151.25+6952.5-5265+1770-200
=-3240+6952.5-5265+1770-200
=3712.5-5265+1770-200
=-1552.5+1770-200
=217.5-200
=17.5
Answer:120*1.5^5-820*1.5^4+2060*1.5^3-2340*1.5^2+1180*1.5-200=17.5
