A number, x, multiplied by itself once is x^2, not x.
The number, x, multiplied by itself twice is then x^3.
The number, x, multiplied by itself three times is then x^4.
So that the number, x, multiplied by itself five times is x^6, not x^5.
Thus x is the 6th root of -243 and you can use de Moivre's formula to find this complex root.
The six roots are the complex numbers:
2.4980*[sqrt(3)/2 + i/2]
2.4980*[i]
2.4980*[-sqrt(3)/2 + i/2]
2.4980*[-sqrt(3)/2 - i/2]
2.4980*[- i/2]
2.4980*[sqrt(3)/2 - i/2].
It is: -3 because -3^5 = -243
No, it's not. 243 is divisible by 3 and 81. To be prime, a number's only factors must be 1 and itself.

243 x 3 = 729
Because three to fifth power means 3 multiplied by itself five times. So, 3 x 3 x 3 x 3 x 3 = 243
243, i had trouble with that question to! but its hard doing those numbers.27 multiplied by 9 is 243.
The number is 243 because 243/243 = 1 and any number divided by itself is always equal to 1
81% multiplied by 300 equals 243
243 is a composite number because it has factors other than 1 and itself. The factors of 243 are 1, 3, 9, 27, 81, and 243.
