Answer:

The answer is 50,000.

Step-by-step explanation:

In order to determine the value, we have to know about the notation numbers.

In any number, every digit has a notation depending on its position.

I have attached an image that shows some notations.

We can know that the nearest ten thousands position is the fifth digit on the left of the decimal point.

To round a number, we have to see the next digit. If the digit is equal or greater than 5, we have to increase the number by one. Otherwise, the number is the same than the original.

In this case, according to the image, the digit is 4 and the next digit is 5, so we have to increase the final digit by one.

Finally, the rounded number to the nearest ten thousands is 50,000.

Answer:
6√3

Explanation:
Before we begin, remember the following:
$\sqrt{a*b} = \sqrt{a} * \sqrt{b}$
$m \sqrt{a} + n \sqrt{a} = (m+n) \sqrt{a}$

Now, for the given:
75 can be written as 25*3
This means that:
$\sqrt{75} = \sqrt{25*3}$
Applying the above concept, we can find that:
$\sqrt{75} = \sqrt{25*3} = \sqrt{25} * \sqrt{3}$
Now, we know that:
√25 = 5 (we ignored the negative value)

This means that:
√75 = 5√3

Finally, we can compute the needed sum as follows:
√75 + √3 = 5√3 + √3 = 6√3

Hope this helps :)
