Question

tính:

\(m.\left(\sqrt{6}+2\right)\left(\sqrt{6}-3\right)\)

Answer 1

\(\left(\sqrt{6}+2\right)\left(\sqrt{6}-3\right)=\sqrt{6}^2-3\sqrt{6}+2\sqrt{6}-6\)

\(=-\sqrt{6}\)

Answer 2

\(=6-3\sqrt{6}+2\sqrt{6}-6=-\sqrt{6}\)

Answer 3

Answer 4

(√6+2)(√6−3)

=\(\sqrt{6}.\sqrt{6}-3\sqrt{6}+2\sqrt{6}-6\)

= \(6-\sqrt{6}-6\)

= \(-\sqrt{6}\)
