Question

Упрости выражение:
(√10-5√3)²

Answer 1

=√10*√10-2*√10*5√3+5√3*5√3= 10-10√30+75= 85-10√30

Answer 2

$( sqrt{10} - 5 sqrt{3} ) {}^{2} \ (a - b) {}^{2} = a {}^{2} - 2ab + b {}^{2} \ ( sqrt{10) {}^{2} } - (2 times sqrt{10 times } 5 sqrt{3} ) + (5 sqrt{3} ) {}^{2} \ 10 - 10 sqrt{30} + 75 \ 85 - 10 sqrt{30}$
