Step-by-step explanation:

Using the rule of radicals

$\sqrt{a}$ × $\sqrt{b}$ ⇔ $\sqrt{ab}$ and $\sqrt{a}$ × $\sqrt{a}$ = a

Given

( $\sqrt{3}$ + $\sqrt{7}$ )( $\sqrt{7}$ - $\sqrt{3}$ )

Each term in the second factor is multiplied by each term in the first factor, that is

$\sqrt{3}$ ( $\sqrt{7}$ - $\sqrt{3}$ ) + $\sqrt{7}$ ( $\sqrt{7}$ - $\sqrt{3}$ ) ← distribute both parenthesis

= $\sqrt{21}$ - 3 + 7 - $\sqrt{21}$ ← collect like terms

= 4
