could somebody tell me the answer or order of operations to this calculation.

3cos(2 x 2)

thanks.

I assume you meant

3cos(2x²)

pick your x
square it
multiply it by 2
take its cosine
multiply by 3

press the = sign on your calculator after each step to overwrite any build-in order of operation

The order of operations for the calculation 3cos(2x²) is as follows:

1. First, pick a value for x.
2. Square the value of x.
3. Multiply the squared value of x by 2.
4. Take the cosine of the result obtained in step 3.
5. Multiply the cosine by 3.

To calculate this expression, you will need to use a calculator. Make sure to perform each step in order and press the = sign on your calculator after each step to overwrite any built-in order of operations.
