Question

How can you rewrite 8 1/2 using a root?(1 point)

Answer 1

To rewrite \( 8 \frac{1}{2} \) using a root, first convert the mixed number into an improper fraction or a decimal.

1. **Convert to decimal**:
\[
8 \frac{1}{2} = 8 + \frac{1}{2} = 8 + 0.5 = 8.5
\]

2. **Express as a root**:
You can express \( 8.5 \) as a fraction:
\[
8.5 = \frac{17}{2}
\]

Now we can use a square root to express \( 8.5 \):
\[
8.5 = \sqrt{72.25}
\]
(since \( \sqrt{72.25} = 8.5 \))

Thus, you can rewrite \( 8 \frac{1}{2} \) as \( \sqrt{72.25} \).
