• Bom... vamos lá, baby!

$a) \: \: {\purple{( \sqrt{15}) {}^{2} }} \\ \\ {\purple{ \sqrt{15} {}^{2} }} \\ \\ {\purple{15}}$

$b) \: \: {\purple{(3 \sqrt{7}) {}^{2} }} \\ \\ {\purple{3 {}^{2} \times \sqrt{7} {}^{2} }} \\ \\ {\purple{9 \times \sqrt{7 {}^{} } {}^{2} }} \\ \\ {\purple{9 \times 7}} \\ \\ {\purple{63}}$

$c) \: \: {\purple{( \sqrt{7} + \sqrt{3} ) {}^{2} }} \\ \\ {\purple{ \sqrt{7 } {}^{2} + 2 \sqrt{7} \sqrt{3} + \sqrt{3} {}^{2} }} \\ \\ {\purple{7 + 2 \sqrt{7} \sqrt{3} + \sqrt{3} {}^{2} }} \\ \\ {\purple{7 + 2 \sqrt{21} + \sqrt{3} {}^{2} }} \\ \\ {\purple{7 + 2 \sqrt{21} + 3 }} \\ \\ {\purple{10 + 2 \sqrt{21} }} \\ \\ {\purple{}}$

$d) \: \:{\purple{(3 - \sqrt{7}) {}^{2} }} \\ \\ {\purple{3 {}^{2} - 2 \times 3 \sqrt{7} + \sqrt{7} {}^{2} }} \\ \\ {\purple{9 - 2 \times 3 \sqrt{7} + \sqrt{7} {}^{2} }} \\ \\ {\purple{9 - 6 \sqrt{7} + \sqrt{7} {}^{2} }} \\ \\ {\purple{9 - 6 \sqrt{7} + 7 }} \\ \\ {\purple{16 - 6 \sqrt{7} }} \\ \\ {\purple{}}$

${\purple{Keep \: loving...}}$
