WitrynaAn imaginary number is a complex number that can be written in the form of a real number multiplied by an imaginary part, named i. This imaginary part i is defined by the property. {i}^ {2}=-1 i2 = −1. . Although it might be difficult to intuitively map imaginary numbers to the physical world, they do easily result from common math operations. WitrynaThis activity is designed to help students practice reducing square roots involving negative numbers. Helps students with rewriting negative square roots as imaginary numbers and identifying if they need to use an i or a negative sign.For each perfect square from 1 to 64, students will reduce each variation: SqRt(a), SqRt(-a), -SqRt(a) …
