Question

Giải chi tiết giúp mik vs ạ 

Answer 1

b: \(=-3+3\sqrt{6}+4+2\sqrt{6}-12-4\sqrt{6}-\sqrt{6}=-11\)

c: \(=\left(\sqrt{3}+1-6-3\sqrt{3}+\dfrac{15}{2}+\dfrac{5}{2}\sqrt{3}\right)\left(5+\sqrt{3}\right)\)

\(=\left(\dfrac{1}{2}\sqrt{3}+\dfrac{5}{2}\right)\left(5+\sqrt{3}\right)\)

\(=\dfrac{1}{2}\left(28+10\sqrt{3}\right)=14+5\sqrt{3}\)

e: \(=-1+\sqrt{2}-\sqrt{2}+\sqrt{3}-...-\sqrt{99}+\sqrt{100}\)

=10-1

=9
