Use square roots to solve the
equation x2 = -121 over the
complex numbers.

x = ±11i

Step-by-step explanation:

x^2 = -121

Take the square root of each side

sqrt(x^2) = sqrt(-121)

sqrt(x^2) = sqrt (-1) *sqrt(121)

We know that the sqrt(-1) is i

x = i ( ±11)

x = ±11i

spinning a 1, 2, or 3. option d.

step-by-step explanation: when spinning a number graph up to 4, and aiming for any number less than 3, that automatically eliminates the number 4. now you have two numbers to spin on that are less than 3, but the number 3 is included in this question because it's no greater of an number than itself. i hope this you : )
