The expression you have is:

$(2^2 \times 3)^3 \times x$

Let's break it down:

1. First, simplify $2^2$: $2^2 = 4$ So, the expression becomes: $(4 \times 3)^3 \times x$

2. Now, simplify $4 \times 3$: $4 \times 3 = 12$ So, the expression becomes: $(12)^3 \times x$

3. Next, cube $12$: $12^3 = 12 \times 12 \times 12 = 1728$ So the expression simplifies to: $1728 \times x$

Thus, the simplified expression is:

$1728x$
