8x to the second power times 3x to the second power (8x)2 + (3x)2 = 64x2 + 9x2 = 73x2 is one possibility, except the problem called for multiplication which would make the answer 64x squared times 9x squared = 576x to the fourth power It could also be read this way: 8x squared times 3x squared equals 24x to the fourth power. I wish my computer would do those cool little twos.

Your question is ambiguous. (3x)^3 times (3x)^3 = 27x^3 times 27x^3 = 729x^6 or, if you meant 3x^3 times 3x^3 = 9x^6
3x2 can be called "three times x squared", "three x squared", or "three times x to the power of two".
This depends on how you place the parenthses- do you mean (3x) all to the second power or 3 times x to the second? In the first case, the 3 becomes 9 and so the answer is 9 times 25= 225. In the second case, the answer is 3 times 25 = 75.
