Answer:

#sqrt 3#

Explanation:

collect like terms - all the numbers are multiples of the radical #sqrt(3)#.

in other words, use operations on the multiples of #sqrt3# and then multiply your answer by #sqrt3#.

BIDMAS means that addition comes before subtraction, and therefore:

#4 + 2 -5 = (4+2) - 5#
#=6-5#
#=1#

then multiply #1# by #sqrt3#

#1 * sqrt3 = sqrt3#
