The double of 6 is 12. 12 squared is 144.
I believe it would be 9, because negative three's negative would be 9 (double negative)
Three squared to the second power is 81.
25
nine
9

No, three squared is nine. 3(squared sign) =3x3 =9
14 squared = 196, so you're looking for the sqrt of double that, ie 392, which is almost exactly 19.8
2x squared can best be describe as some variable being double and then squared.
3 squared=9 3 squared=3*3 3*3=9
3 squared is 3 x 3 or 9.
