Full solution

Q. Multiply. Write your answer in simplest form.\newline5(35)-\sqrt{5}(3 - \sqrt{5})
  1. Distribute 5-\sqrt{5}: Distribute 5-\sqrt{5} to both terms inside the parentheses.-\sqrt{\(5\)}(\(3 - \sqrt{55}) = -\sqrt{55}\cdot 33 - \sqrt{55}\cdot(-\sqrt{55})
  2. Simplify first term: Simplify the first term. 5×3=35-\sqrt{5} \times 3 = -3\sqrt{5}
  3. Simplify second term: Simplify the second term using the property that aa=a\sqrt{a} \cdot \sqrt{a} = a.5(5)=55=5-\sqrt{5} \cdot (-\sqrt{5}) = \sqrt{5} \cdot \sqrt{5} = 5
  4. Combine results: Combine the results from Step 22 and Step 33.\newline35+5-3\sqrt{5} + 5
