Explanation: Before we begin, remember the following:
Now, for the given: 75 can be written as 25*3 This means that: Applying the above concept, we can find that: 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
