Any number multiplied by itself or taken to the second power is said to be squared.

Oh, dude, you're hitting me with some math lingo! So, when you see X to the power of 2 plus Y to the power of 2, you're basically looking at X squared plus Y squared. It's like those little numbers are getting all squared up and ready to party together in a math equation.
Square means to multiply by itself. For example, 2 squared=2 x 2=4, or 8 squared=8 x 8=64
Raising a number to the second power means you are squaring the number, multiplying it by itself. 2 squared= 2*2=4 3 squared=3*3=9
It means the average
To find the product of x squared and 2x squared, you multiply the coefficients (2 and 1) to get 2, and then add the exponents of x (2 and 2) to get x to the power of 4. Therefore, x squared times 2x squared is equal to 2x^4.
