[1/1 Formula]
    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
