Correct Answer

D

Explanation

To find the values of a and b in the expression a√5 + b√2, we need to equate it to the given expression √(95 - 30√10). By comparing the coefficients of √5 and √2 on both sides, we can determine the values of a and b.On the left side, we have a√5 + b√2.On the right side, we have √(95 - 30√10).Comparing the coefficients of √5, we get:a = 0Comparing the coefficients of √2, we get:b = -30Therefore, the values of a and b are 0 and -30, respectively.
