Question 153418
{{{11sqrt(-12)(-12sqrt(-1))}}}
={{{11sqrt((-1*12))(-12sqrt(-1))}}}         ...................(-1 = i^2)
={{{11sqrt((3*2^2*i^2))(-12sqrt(i^2))}}}
={{{11*2i*sqrt(3)(-12i)}}}
={{{11*2*(-12)i^2sqrt(3)}}}
={{{11*2*(-12)(-1)sqrt(3)}}}                ...................(i^2 = -1)
={{{264sqrt(3)}}}
