(9x2 + 7)(9x2 - 7) = 81x4 - 49
3.14 times 7 squared is equal to 153.86
n^3 mean a number Squared by 3
If you mean: x squared+9x+14 = 0 then by using the quadratic equation formula x = -2 or x = -7
If you mean a2 x a2... the answer is a4
if you mean why is 7 called 7 squared, because it's a short way of saying 7x7 and for short it's 7 squared or 7 with a little 2 next to it on the top right hand corner, and the answer is 49.
