much simpler 简单得多
例：
rather than trying to find the book you lost,it is much simpler to buy a new one
与其试图找回你丢失的那本书,还是买一本新的书简单得多
没有 much simple 这个说法
除非 much simple 的 much 是前半句的一部分,
比如
How much simple interest does $2,000 earn in 7 months at an interest rate of 5%?
这里 much 和 simple 不组成一个短语,
much 和前面的 how 成为 how much ,意思是多少.
