摘要 This expression is a bit difficult to interpret as there seems to be several decimal points and no clear order of operations. However, assuming we use the standard order of operations (PEMDAS), we can simplify this expression as follows:4 + 7x3 + 0.28 + 15 + 3x3 + 0.28First, we perform the multiplication: 4 + 21 + 0.28 + 15 + 9 + 0.28 Next, we add up all the numbers: 49.56 Therefore, the simplified expression is 49.56.

This expression is a bit difficult to interpret as there seems to be several decimal points and no clear order of operations. However, assuming we use the standard order of operations (PEMDAS), we can simplify this expression as follows:4 + 7x3 + 0.28 + 15 + 3x3 + 0.28First, we perform the multiplication: 4 + 21 + 0.28 + 15 + 9 + 0.28 Next, we add up all the numbers: 49.56 Therefore, the simplified expression is 49.56.

我还是有些不太明白，回答能否再详细些？

这个表达式有点难解释，因为似乎有几个小数点，没有cl的操作耳朵顺序Howeve"，假设我们使用的是标准的运算顺序(PEMDAS)，那么可以把这个表达式简化为:4+7x3+0.28+15+3x3+0.28首先，我们执行最后通牒:4+21+0.28+15+9+0.28接下来，我们把所有的数字加起来:49.56因此，si隆起的表达式是49.56
