Full solution

Q. Multiply. Write your answer in simplest form. \newline5(72)-\sqrt{5}(7 - \sqrt{2})
  1. Distribute 5-\sqrt{5}: Distribute 5-\sqrt{5} to both terms inside the parentheses.-\sqrt{\(5\)}(\(7 - \sqrt{22}) = -\sqrt{55}\cdot 77 - \sqrt{55}\cdot(-\sqrt{22})
  2. Multiply 5-\sqrt{5} by 77: Multiply 5-\sqrt{5} by 77.\newline5×7=75-\sqrt{5} \times 7 = -7\sqrt{5}
  3. Multiply 5-\sqrt{5} by 2-\sqrt{2}: Multiply 5-\sqrt{5} by 2-\sqrt{2}.5×(2)=5×2=10-\sqrt{5} \times (-\sqrt{2}) = \sqrt{5 \times 2} = \sqrt{10}
  4. Combine results: Combine the results from Step 22 and Step 33.\newline75+10-7\sqrt{5} + \sqrt{10}
