What are the solutions to x^3 = −4 + 4i in polar form?

The polar form is =5( cos 126.9 º+is in 126.9 º )

Step-by-step explanation: Let z=a+ ib a complex number

The polar form is z=r(cosθ+i sin θ)

r=√a 2+b 2

Here, we have z=−3+4 i

∴r=√9+16=√25=5

z=5(−3/5+4i/5)

∴cosθ=−3 and sinθ=4/5

So, θ is in the second quadrant

θ=126.9 º z=5(cos 126.9 º+i sin 126.9 º)

c.

step-by-step explanation:

she should of added 9^2 and 12^2. that is because it is a^2+b^2=c^2. c^2 is the hypotenuse and should always be bigger than the other two numbers. which is why she should of added 9 squared and 12 squared together instead of 15 squared.
