So now we can deal with an X |
||
| that has an exponent or a root. | ||
| But what do we do with this? | ||
|
3X2 = 12 |
||
| Do we try to get the 3 away from the X first? | ||
| Do we try to get rid of the exponent first? | ||
| To better see what you should do, | ||
| rewrite this without any exponents. | ||
| Use multiplication instead ... | ||
|
3 × X × X = 12 |
||
| Does that help? | ||
| The first thing we do is | ||
| get rid of the stuff that is not an X. | ||
| That means we need to lose the 3. | ||
| In this problem, the 3 is multiplied times the X's | ||
| so we need division to peel it away ... | ||
|
|
||
| Now get rid of the exponent with a root ... | ||
