question 207

Multiple Choice

Multiply, and then simplify if possible. Assume all variables represent positive real numbers.
- $( \sqrt { 77 } - \sqrt { 847 } ) ( \sqrt { 11 } + \sqrt { 7 } )$

• A) \(11 \sqrt { 7 } + 7 \sqrt { 11 } - 11 \sqrt { 77 } + 77\)
• B) \(11 \sqrt { 7 } + 7 \sqrt { 11 } - 11 \sqrt { 77 } - 77\)
• C) \(11 \sqrt { 7 } + 7 \sqrt { 11 } + 11 \sqrt { 77 } + 77\)
• D) \(11 \sqrt { 7 } - 7 \sqrt { 11 } + 11 \sqrt { 77 } + 77\)
