Square Root Negative 1

Square Root Negative 1 The numbers written inside the square root radical can be either 0 or any positive integer in order to get a real solution as the y value. If a negative number is written inside the square root, then the output becomes an imaginary number, commonly represented by i. Square root of -1, which can also be written as -1 is called as the imaginary number and it is not considered a real number. -1 is equal to i which means the value of i = -1. Example 1: What is the simplified form of -12? -12 is an imaginary number since it consists the negative sign inside the radical. -12 can also be written as: (-1 * 12). This is equal to -1 * 12 and here -1 is the i value and is the imaginary number. Hence we get: -12 = i * 12 and now we can simplify 12. This implies: -12 = i * (2* 2* 3) = i * 23. Therefore the simplified form of -12 = 2i3. Example 2: What is the simplified form of -18? -18 is an imaginary number since it consists the negative sign inside the radical. -18 can also be written as: (-1 * 18). This is equal to -1 * 18 and here -1 is the i value and is the imaginary number. Hence we get: -18 = i * 18 and now we can simplify 18. This implies: -18 = i * (2 * 3 * 3) = i * 32. Therefore the simplified form of -18 = 3i2.
