Web21 de jun. de 2024 · Mathematicians use i to represent the square root of minus one. This is called the imaginary unit - it is not a real number, does not exist in ‘real’ life. We can use it to find the square roots of negative numbers though. If I want to calculate the square roots of -4, I can say that -4 = 4 × -1. WebWe used an imaginary number (5 i) and ended up with a real solution (−25). Imaginary numbers can help us solve some equations: Example: Solve x 2 + 1 = 0 Using Real Numbers there is no solution, but now we can solve it! Subtract 1 from both sides: x 2 = −1 Take the square root of both sides: x = ± √ (−1) x = ± i Answer: x = −i or +i Check:
