Subtract 10/15-4√15.

Answer 1

To solve the expression \( \frac{10}{15} - 4\sqrt{15} \), we will first simplify \( \frac{10}{15} \).

\[ \frac{10}{15} = \frac{2}{3} \]

Now we can rewrite the expression:

\[ \frac{2}{3} - 4\sqrt{15} \]

This expression cannot be simplified further, as \( 4\sqrt{15} \) is not a fraction and cannot combine with \( \frac{2}{3} \).

Thus, the final answer is:

\[ \frac{2}{3} - 4\sqrt{15} \]

Answer 2

A. 6√0
B. 6√30
C. 6√15
D. √90

Answer 3

It seems you are asking which of the options A, B, C, or D is equivalent to a particular expression. However, you haven't provided that expression. Let's evaluate each of the options to see if any might match or simplify to a common expression.

1. A. \( 6\sqrt{0} = 6 \cdot 0 = 0 \)

2. B. \( 6\sqrt{30} \) remains as is.

3. C. \( 6\sqrt{15} \) remains as is.

4. D. \( \sqrt{90} = \sqrt{9 \cdot 10} = 3\sqrt{10} \)

Now, we compare all the options:

• A is \( 0 \)
• B is \( 6\sqrt{30} \)
• C is \( 6\sqrt{15} \)
• D is \( 3\sqrt{10} \)

If you provide the context or the expression you are comparing to, I could help identify which of these is equivalent or relevant!
