Work: Calculate the value of equation 4.5^2+5^2+5.5^2+6^2+6.5^2+7^2+7.5^2+8^2 .
Question type: Mathematical calculation
Solution:
4.5^2+5^2+5.5^2+6^2+6.5^2+7^2+7.5^2+8^2
=20.25+5^2+5.5^2+6^2+6.5^2+7^2+7.5^2+8^2
=20.25+25+5.5^2+6^2+6.5^2+7^2+7.5^2+8^2
=20.25+25+30.25+6^2+6.5^2+7^2+7.5^2+8^2
=20.25+25+30.25+36+6.5^2+7^2+7.5^2+8^2
=20.25+25+30.25+36+42.25+7^2+7.5^2+8^2
=20.25+25+30.25+36+42.25+49+7.5^2+8^2
=20.25+25+30.25+36+42.25+49+56.25+8^2
=20.25+25+30.25+36+42.25+49+56.25+64
=45.25+30.25+36+42.25+49+56.25+64
=75.5+36+42.25+49+56.25+64
=111.5+42.25+49+56.25+64
=153.75+49+56.25+64
=202.75+56.25+64
=259+64
=323
Answer:4.5^2+5^2+5.5^2+6^2+6.5^2+7^2+7.5^2+8^2=323
