7.3×7.3+3.7×7.2等于多少?脱式计算

7.3×7.3+3.7×7.2

Answer 1

脱式计算过过程7.3×7.3+3.7×7.2
解题思路：四则运算规则（按顺序计算、先算乘除后算加减，有括号先算括号，有乘方先算乘方）即脱式运算（递等式计算）需在该原则前提下进行
解题过程：
7.3×7.3+3.7×7.2

=7.3×(7.3+3.7)-3.7×0.1
=80.3-3.7×0.1
=80.3-0.37
=79.93

Answer 2

7.3×7.3 + 3.7 × 7.2
= 7.3×7.3 + 7.3 × 3.7 - 0.37
= 7.3 × 11 - 0.37
= 73 + 7.3 - 0.37
= 73 + 6.93
= 79.93
