How do you solve sqrt(-32) with imaginary numbers?

I would be so grateful if you helped me out! Tell me specifically how to do it, as well because I wanna know.How do you solve sqrt(-32) with imaginary numbers?
If you are using imaginary numbers then you first of all change 鈭?-32) into 鈭?2 times 鈭?-1). You can do this because -1 x 32 = -32.


鈭?-1) is equal to 'i' - this is just the definition of 'i' when you're working with imaginary number, and to get the 鈭?2 you just use your calculator.


Your final answer in this case is 5.7iHow do you solve sqrt(-32) with imaginary numbers?
sqrt(-32) = sqrt(16 * (-2)) =


4 * sqrt( (-1) * 2 ) =


4 * sqrt(-1) * sqrt(2) =


4 * i *鈭?
