Question

Add 28–√+38–√ .

Answer 1

Bot, that's incorrect

Answer 2

Bot, you need to add it, not simplify it

Answer 3

To simplify the expression \( \sqrt{28} + \sqrt{38} \), we first simplify each square root if possible.

1. Simplifying \( \sqrt{28} \):
\[
\sqrt{28} = \sqrt{4 \cdot 7} = \sqrt{4} \cdot \sqrt{7} = 2\sqrt{7}
\]

2. Next, we simplify \( \sqrt{38} \):
\[
\sqrt{38} = \sqrt{2 \cdot 19} \quad \text{(does not simplify further)}
\]

Now we can combine the simplified square roots:
\[
\sqrt{28} + \sqrt{38} = 2\sqrt{7} + \sqrt{38}
\]

Thus, the expression \( \sqrt{28} + \sqrt{38} \) simplifies to:
\[
2\sqrt{7} + \sqrt{38}
\]

This is the simplified form, as \( 2\sqrt{7} \) and \( \sqrt{38} \) cannot be combined further. So, the final answer is:
\[
2\sqrt{7} + \sqrt{38}
\]

Answer 4

I apologize for any confusion. Let's re-evaluate the expression \( \sqrt{28} + \sqrt{38} \) step by step:

1. **Finding \( \sqrt{28} \)**:
\[
\sqrt{28} = \sqrt{4 \times 7} = \sqrt{4} \times \sqrt{7} = 2\sqrt{7}
\]

2. **Finding \( \sqrt{38} \)**:
\[
\sqrt{38} = \sqrt{2 \times 19} \quad \text{(this does not simplify further)}
\]

Now combining these results:
\[
\sqrt{28} + \sqrt{38} = 2\sqrt{7} + \sqrt{38}
\]

This is indeed the correct simplification. If you were referring to something else or a different calculation, please clarify, and I would be happy to assist you further!

Answer 5

I apologize for the misunderstanding. Let's go ahead and add the two square roots together properly:

The expression is:
\[
\sqrt{28} + \sqrt{38}
\]

1. **Calculate \( \sqrt{28} \)**:
\[
\sqrt{28} \approx 5.2915
\]

2. **Calculate \( \sqrt{38} \)**:
\[
\sqrt{38} \approx 6.1644
\]

Now we add these approximate values:
\[
5.2915 + 6.1644 \approx 11.4559
\]

So,
\[
\sqrt{28} + \sqrt{38} \approx 11.46 \text{ (to two decimal places)}
\]

If you need the exact sum or any further calculations, please let me know!
