化简算式

A=(√54)-(√24)-[√(2/3)]+[1/(√6)]
=(√3^2*6)-(√2^2*6)-[√(6/3^2)]+√(6/6^2)，
=3√6-2√6-(1/3)√6+(1/6)√6
=(3-2-1/3+1/6)*√6
=5(√6)/6

A=(√54)-(√24)-[√(2/3)]+[1/(√6)]
=3√6-2√6-[(√6)/3）+(√6)/6]
=(√6)-[(√6)/2]
=(√6)/2

A = (√54)-(√24)-[√(2/3)]+[1/(√6)]
= 3√6 - 2√6 - (√6)/3 + (√6)/6
= (3 - 2 - 1/3 + 1/6)*√6
= (5√6)/6
