It seems like you've provided a mathematical expression that includes some numbers and trigonometric functions. However, the expression is not entirely clear, and it's missing some operators. Let me try to interpret what you might be asking for.

If you want to calculate the value of the expression: 54√2 * sin(315°) * cos(300°)

First, we can calculate the trigonometric values:

sin(315°) = sin(360° - 45°) = -sin(45°) = -√2/2 cos(300°) = cos(360° - 60°) = cos(60°) = 1/2

Now, you can multiply the values together:

54√2 * (-√2/2) * (1/2)

Now, calculate the result:

= 54√2 * (-√2/2) * (1/2) = (54 * √2 * -√2) / (2 * 2) = (-54 * 2) / 4 = -108 / 4 = -27

So, the value of the expression is -27.
