Question

What is √​−196?
I am super confused. Please help.

Answer 1

you are entering the realm of complex numbers
i = √-1
That is, i^2 = -1
√-196 = √(196 * -1) = √196 * √-1 = 14i

better start reading on the topic.

Answer 2

Ok, Thank you soooo much!

Answer 3

√​−196 is not defined as a real number, rather it is imaginary. We can define √​−196 as the product of √​196 and √​−1. Since √​−1=i, then √​−196=±14i.

Answer 4

Not quite, AJ+L
√196 is 14
not ±14
It happens that (-14)^2 = 196, but the square root is defined as the positive number
