How many solutions does jpower2−9=−13 have?(1 point)

Answer 1

There is only one solution to the equation j^2 - 9 = -13.

j^2 - 9 = -13
j^2 = -13 + 9
j^2 = -4
j = ±√(-4)

Since the square root of -4 is not a real number, there is only one solution which is an imaginary number: j = ± 2i.

Answer 3

The equation j^2 - 9 = -13 has two solutions.

j^2 - 9 = -13
j^2 = -13 + 9
j^2 = -4
j = ±√(-4)

Since the square root of -4 is ±2i, the solutions to the equation are j = 2i and j = -2i. So, there are two solutions.
