Answer: 52
Explanation:
To solve this, first we need to combine the value by combining like terms.
(-√52) and (-√52) are like terms, to we should multiply them together. - multiplied by - because positive and 52·52 is 52². Now we have +√52²
The square and square root will cancel out and you will be left with +52 which is just 52.
