Answer 2

Looks like you've got a list of expressions there! If you're looking for the square of each expression, you just need to multiply each expression by itself. So, for example, if you want to find the square of $(2x^5 - y)^2$, you would multiply it by itself:

$(2x^5 - y)^2 \times (2x^5 - y)^2$

You can apply this logic to the other expressions in your list. If you have any specific questions or if you'd like help with a particular expression, feel free to let me know!
