Answer:
Since (√(3) + √(10) - √(5))(√(3) + √(10) + √(5)) = (√(3)+√(10))2 - (√(5))2 = 3 + 10 + 2√(3)√(10) - 5 = 8 + 2√(30) and , (8 + 2√(30))(8 ...
This is correct answer
Since (√(3) + √(10) - √(5))(√(3) + √(10) + √(5)) = (√(3)+√(10))2 - (√(5))2 = 3 + 10 + 2√(3)√(10) - 5 = 8 + 2√(30) and , (8 + 2√(30))(8
