No it is not.
81 A number raised to the second power is the number multipled by itself twice (9*9). A number raised to the third power, is the number multipled by itself 3 times (9*9*9) and so on.
23 * 32 * 5 = 8 * 9 * 5 = 360
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.
3²=3x3=9
