Formal Translation:
```
学习并理解以下成语的含义。
```

Casual Translation:
```
学习并搞懂下面这些成语的意思。
```

Explanation:
In the formal translation, the expression "理解" (understand) is used, which is a more formal way of saying "搞懂" (get/figure out) used in the casual translation. The formal version also uses the more formal term "含义" (meaning) instead of "意思" (meaning) used in the casual version.
