Quizplus · Accepted Answer

This expression is in the form of $(a+b)(a-b)$, which simplifies to $a^2 - b^2$. Here, $a = \sqrt{10}$ and $b = \sqrt{2}$, so the expression simplifies to $(\sqrt{10})^2 - (\sqrt{2})^2 = 10 - 2 = 8$.

Simplify - (10+2)(10−2)( \sqrt { 10 } + \sqrt { 2 } ) ( \sqrt { 10 } - \sqrt { 2 } )(10​+2​)(10​−2​)

Simplify
- $( \sqrt { 10 } + \sqrt { 2 } ) ( \sqrt { 10 } - \sqrt { 2 } )$
