Full solution

Q. Multiply. Write your answer in simplest form. \newline5(65)-\sqrt{5}(-6 - \sqrt{5})
  1. Distribute and Multiply: Distribute 5-\sqrt{5} to both terms inside the parentheses.-\sqrt{\(5\)}(\(-6 - \sqrt{55}) = -\sqrt{55}(6-6) - \sqrt{55}(-\sqrt{55})
  2. Multiply by 6-6: Multiply 5-\sqrt{5} by 6-6.5(6)=65-\sqrt{5}\cdot(-6) = 6\sqrt{5}
  3. Multiply by 5-\sqrt{5}: Multiply 5-\sqrt{5} by 5-\sqrt{5}.
    5×(5)-\sqrt{5}\times(-\sqrt{5})
    = 5×5\sqrt{5}\times\sqrt{5}
    = 55
  4. Combine Results: Combine the results from Step 22 and Step 33.\newline65+56\sqrt{5} + 5
