Answer 2

Let's first simplify the expression inside the parentheses using the distributive property of multiplication:

(√7+√3)² = (√7)² + 2(√7)(√3) + (√3)² = 7 + 2√21 + 3 = 10 + 2√21

Now we can substitute this expression into the original equation:

(√7+√3)² - √84 = (10 + 2√21) - (√4*21) = 10 + 2√21 - 2√21 = 10

Therefore, the solution is 10.
