Suppose cell B3 contains the value 49. When you use the formula SQRT(B3), it will calculate the square root of 49, which is 7. This means that if you multiply 7 by itself (7 * 7), you will get the value 49. Similarly, if B3 contains the value 36, applying the formula SQRT(B3...
That’s where imaginary numbers come in. The square root of -1 is defined asi, which stands for “imaginary unit.” So: √(-49) = √49 ×√(-1) = 7i Even though they’re called “imaginary,” these numbers have real-world uses. Engineers use them to model electrical circuits. Phy...
