Answer 1

Answer:

(1) (5+√2)(3--√3)

=15-5√3+3√2+√6

(2) (7+√3)(7-√3)

=(7)²-(√3)²

=49-3

=46

Answer 2

Answer:

$\mathbb\red{Ꭺŋѕwєr}$

$1.)(5 + \sqrt{2} )(3 - \sqrt{3} )$

$5 \times 3 + 5 \times ( - \sqrt{3} ) + \sqrt{2} \times 3 + \sqrt{2} \times ( - \sqrt{3} )$

$15 - \sqrt[5]{3} + \sqrt[3]{2} - \sqrt{6}$

$2.)(7 + \sqrt{3} )(7 - \sqrt{3} )$

${7}^{2} - ( \sqrt{3} ) {}^{2}$

$49 - ( \sqrt{3} ) {}^{2}$

$49 - 3$

$46$
