bot can you answer asap
The correct answer is 10 sqrt 21.
To add √26 + √28, we can simplify both square roots individually and then add them together.
√26 can be further simplified by finding the largest perfect square that divides 26 evenly. 26 is between 25 (5^2) and 36 (6^2), so the largest perfect square that divides 26 evenly is 25. Therefore, we can write:
√26 = √(5^2 × 2) = 5√2
Similarly, √28 can be simplified by finding the largest perfect square that divides 28 evenly. 28 is between 25 (5^2) and 36 (6^2), so the largest perfect square that divides 28 evenly is 25. Therefore, we can write:
√28 = √(4 × 7) = 2√7
Now we have:
5√2 + 2√7
Since the two terms have different radicands (2 and 7), they cannot be combined any further.
Therefore, the final answer is:
5√2 + 2√7
To add √26 and √28, you need to first simplify each of the square roots:
√26 can be written as √(13 * 2), which can be further simplified as √13 * √2.
Similarly, √28 can be written as √(14 * 2), which can be further simplified as √14 * √2.
Now, adding the simplified terms together:
√13 * √2 + √14 * √2 can be rewritten as (√13 + √14) * √2.
Therefore, the answer is (√13 + √14) * √2.
Please note that it is not possible to simplify this further.

To add √19 + √19, we can simply add the two square roots together:
√19 + √19 = 2√19
Therefore, the answer is 2√19.
Add 22−−√3 + 322−−√ + 22−−√ .(1 point)
To add √3 + √32 + √2, we need to simplify each square root individually and then add them together.
√3 is already simplified, so we don't need to make any changes to it.
To simplify √32, we can find the largest perfect square that divides 32 evenly. 32 is between 25 (5^2) and 36 (6^2), so the largest perfect square that divides 32 evenly is 4. Therefore, we can write:
√32 = √(4 × 8) = 2√8
Similarly, we can simplify √2 by leaving it as it is.
Now we have:
√3 + 2√8 + √2
Since the terms have different radicands (3, 8, and 2), they cannot be combined any further.
Therefore, the final answer is:
√3 + 2√8 + √2.
