Answer 2

Explicație pas cu pas:

5.

a) =(√3)²+√2√3=

=3+√2√3=

=3+√6;

b) =√2√6-2√2√10=

=√2√2√3-2√2√10=

=2√3-2√2√10=

=2√3-2√2√2√5=

=2√3-2×2√5=

=-4;

c) =3(2√5+√3)-√3(√5+3)=

=6√5+3√3-√3(√5+3)=

=6√5+3√3-(√3√5+3√3)=

=6√5+3√3-(√15+3√3)=

=6√5+3√3-√15-3√3=

=6√5-√15;

d)=3(3√2+√12)√2-√216=

=3(3√2+2√3)√2-√216=

=(9√2+6√3)√2-√216=

=9(√2)²+6√3√2-√216=

=9×2+6√3√2-√216=

=18+6√3√2-√216=

=18+6√6-√216=

=18+6√6-6√6=

=18;

e) =2√5+3√10(3√2-√5)=

=2√5+9√2√10-3√5√10=

=2√5+9√2√2√5-3√5√10=

=2√5+9×2√5-3√5√10=

=2√5+18√5-3√5√10=

=2√5+18√5-3√5√5√2=

=2√5+18√5-3×5√2=

=2√5+18√5-15√2=

=20√5-15√2;

f)

$= \sqrt{6}(3 \sqrt{10 } + \frac{8 \times 2 \sqrt{5} }{2} ) =$

$= \sqrt{6} (3 \sqrt{10} + \frac{16 \sqrt{5} }{2} ) =$

=√6(3√10+8√5)=

=3√6√10+8√6√5=

=3√60+8√6√5=

=3√60+8√30=

=3×2√15+8√30=

=6√15+8√30.
