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

3 to the 2nd power plus 5 x 4 - 9 = 20 32 + 5 x 4 - 9= 9 + 20 - 9= 20
23 * 32 * 5 = 8 * 9 * 5 = 360
It then equals 1/81
5+5*9/3^2 = 5+5*9/9 = 5+5*1 = 5+5 = 10.
8 x 9 x 5 and 4 x 3 x 25 360 and 300 The GCF is 60.

(-3/5)^2 = + 0.36, or...(-3/5)^2 = + 9/25
The value of -3 to the second power is 9.
The question as stated could mean either (9/2)2 or 9/22. The first is 81/4 in lowest terms, while the second is 9/4 in lowest terms.
