To rewrite \( 9 \frac{1}{3} \) using a root, you first need to convert the mixed number into an improper fraction.
-
Convert \( 9 \frac{1}{3} \) to an improper fraction: \[ 9 \frac{1}{3} = \frac{9 \times 3 + 1}{3} = \frac{27 + 1}{3} = \frac{28}{3} \]
-
Now, to express this fraction using a root, you can manipulate it as follows:
- First, find a way to represent \( 28 \) as a root. You can write \( 28 \) as \( 16 + 12 \), or you can express it more simply.
- Notice that \( 28 \) can be expressed as \( \sqrt{784} \) since \( 784 \) is \( 28^2 \).
Thus, we can rewrite \( \frac{28}{3} \) as: \[ \frac{\sqrt{784}}{3} \]
Alternatively, if you're looking for a simpler expression, you can also factor \( 28 \): \[ 28 = 4 \times 7 \] This means it can also be written as: \[ \frac{2\sqrt{7}}{3} \]
However, for a more straightforward expression, the previous form works well.
So, \( 9 \frac{1}{3} \) can be rewritten as: \[ \frac{\sqrt{784}}{3} \] or \(\frac{2\sqrt{7}}{3}\) depending on the context you desire!
