What is √−196?
I am super confused. Please help.
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.
To evaluate the square root of a negative number, we need to introduce the concept of complex numbers. In the real number system, the square root of a negative number is undefined. However, in the complex number system, we can define the square root of a negative number.
The symbol "i" represents the imaginary unit, which is defined as the square root of -1. Using this notation, we can express the answer to the square root of a negative number.
To find the square root of -196, we can rewrite it as √(196 * -1). This can be simplified to √(196) * √(-1), which is 14i.
Therefore, the square root of -196 is 14i.
Ok, Thank you soooo much!
√−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.
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
