See explanation below for the way to simplify this problem:

Explanation:

First, note:

#color(red)((a/b)^x = a^x/b^x)#

Apply this to this problem gives:

#(11/12)^3 = 11^3/12^3#

Now, we can expand and then multiply the terms in the numerator and the terms in the denominator:

#11^3/12^3 = (11 xx 11 xx 11)/(12 xx 12 xx 12) = (121 xx 11)/(144 xx 12) = 1331/1728#
