# How do you simplify \frac { 7a } { 7a ^ { 4} }?

Jan 3, 2017

$\frac{1}{a} ^ \left\{3\right\}$

#### Explanation:

Okay so $\setminus \frac{7 a}{7 {a}^{4}}$ means

$\frac{7 \cdot a}{7 \cdot a \cdot a \cdot a \cdot a}$

When you're in doubt always expand!

When expanding you see the bigger picture, now remember after this we cancel stuff out to make it easier to understand

For example take $\setminus \frac{24}{4}$. On a test would you multiply $\setminus \frac{24}{4}$ or $6$. Which one is easier? Same goes with this!

Cancel the redundant letters and numbers in this case the number $7$ and an $a$.

Now the top part is gone and there is ${a}^{3}$ left. Which is on the bottom but since the top part make sure to put 1 at the top!
