Question

Find the difference.
-2√13 and -5√13

Answer 1

No slashes

Answer 2

And why Is that? No slashes please

Answer 3

Find the Sum: -11√6 + 9√6

Answer 4

To find the difference between \(-2\sqrt{13}\) and \(-5\sqrt{13}\), we can set it up as follows:

\[
-2\sqrt{13} - (-5\sqrt{13}) = -2\sqrt{13} + 5\sqrt{13}
\]

Now, combine the terms:

\[
(-2 + 5)\sqrt{13} = 3\sqrt{13}
\]

So, the difference between \(-2\sqrt{13}\) and \(-5\sqrt{13}\) is:

\[
3\sqrt{13}
\]

Answer 5

Sure! Let's find the difference between -2√13 and -5√13 without using any slashes.

We can rewrite the problem as:

-2√13 - (-5√13)

This simplifies to:

-2√13 + 5√13

Now, combine the terms:

(-2 + 5)√13 = 3√13

So, the difference is:

3√13.

Answer 6

Certainly! Let's break it down step by step:

1. **Understanding the Terms**: We start with two terms: -2√13 and -5√13. Both terms are multiples of √13.

2. **Finding the Difference**: We want to find the difference between -2√13 and -5√13. This can be thought of as subtracting -5√13 from -2√13.

3. **Rewriting the Expression**: We can write this as:
-2√13 - (-5√13)

4. **Removing the Negative**: Subtracting a negative number is the same as adding the positive. So we have:
-2√13 + 5√13

5. **Combining Like Terms**: Now we combine the two terms. Since they both include √13, we just need to combine the coefficients:
(-2 + 5)√13

6. **Calculating the Coefficients**:
-2 + 5 equals 3.

7. **Final Result**: Therefore, we have:
3√13

Thus, the difference between -2√13 and -5√13 is 3√13.

Answer 7

To find the sum of -11√6 and 9√6, we can follow these steps:

1. **Identify the Terms**: We have two like terms: -11√6 and 9√6.

2. **Combine the Coefficients**: Since they are like terms (both include √6), we can simply add their coefficients:
\[
(-11 + 9)√6
\]

3. **Calculate the Coefficients**:
\[
-11 + 9 = -2
\]

4. **Write the Result**: Therefore, the sum is:
\[
-2√6
\]

So, the sum of -11√6 and 9√6 is -2√6.
