Your post is very confusing. You ask us to add, but the parentheses indicate multiplication.

4x power of two = 4x squared = (4x)^2 online = 4x times 4x = 4x * 4x online

Or do you mean 4 * x^2 = 4 * x * x? If this is it, why is there another x rather than indicating x^3?

In other words, are you squaring 4x or merely x? Use parentheses to indicate 4x, e.g., (4x)^2.

Repost using "*" to indicate "times" and "^" to indicate "power of."
