Please help!! This is so confusing! 100 points!!

The value of the expression given is:

Step-by-step explanation:

First, you must divide the expression in three, and to the final, you can multiply it:

Now, we can solve each part one by one:

First part.

And we elevate this to -2:

Second part.

And we elevate this to 4:

Third Part.

At last, we multiply all the results obtained:

We approximate the value because the difference to 4 is minimal, which could be obtained if we use all the decimals in each result.

Step-by-step explanation:

Distributing the power of -2 to the parenthesis,

Distributing the power of 4 to the fraction,

Multiplying,

Simplifying,
