1、  两者都可以表示做某事有意义或者有价值。

   Both can mean it’s meaningful to do something or something is worth doing.

   For example:

   学习中文很有用，花再多时间也 值得 / 值。

   But “值得” is a verb that can be followed by another verb or a clause , while “值”

Is an adjective which is usually not followed by any other element.

   For example:

   别生气了，咱们不值得为这么点小事生气。

   为这么点小事生气，一点儿也不值。

2、两者都可以做动词，但意思不同。“值得”表示价钱相当，合算，后面加动词或动词短语；而“值”表示货物和价钱相当，后面加钱数。

   Both can be used as verbs, yet with different meanings. “值得”means the price is fair , followed by a verb or verb phrase, while “值” means the commodity is worth the price, followed by an amount of money.

   这个沙发价钱不贵，质量又好，值得买。

   这个手机值五千块。
