Full solution

Q. Multiply. Write your answer in simplest form.\newline5(8+3)-\sqrt{5}(8 + \sqrt{3})
  1. Distribute 5-\sqrt{5}: Distribute 5-\sqrt{5} to both terms inside the parentheses.5(8+3)=5×8+5×3-\sqrt{5}(8 + \sqrt{3}) = -\sqrt{5}\times 8 + -\sqrt{5}\times \sqrt{3}
  2. Multiply 5-\sqrt{5} by 88: Multiply 5-\sqrt{5} by 88.\newline5×8=85-\sqrt{5} \times 8 = -8\sqrt{5}
  3. Multiply 5-\sqrt{5} by 3\sqrt{3}: Multiply 5-\sqrt{5} by 3\sqrt{3}.\newline5×3=5×3=15-\sqrt{5} \times \sqrt{3} = -\sqrt{5\times3} = -\sqrt{15}
  4. Combine results: Combine the results from Step 22 and Step 33.\newline8515-8\sqrt{5} - \sqrt{15}
