. It is equal to
.With the same calculation : If the power number (the number on top) is negative, it is quite strange but you must do the following : Now let's have a look at something practical : Hence, by gathering the 3, we see that : We can write : In fact : Also, you have to know that a number to the power 0 is always 1. On the other hand, does not exist , it does not make sense. Now that you know that , you should also know that . Hence : and that 2 to the power 3 to the power 4 is equal to 2 to the power 12 : So : There you go, that's it...You can do the problems to check if you have understood. |
