To find the cube root of a number, we have to find out which number when multiplied by itself twice gives that number. This is the same as trying to find out the length of the side of a cube when ...
Unlike the more familiar real numbers—positive and negative integers, fractions, square roots, cube roots and even numbers such as pi—complex numbers have an imaginary component. This means they are ...
2^2 = 4\). Reversing this gives \(\sqrt{4} = 2\). To find square roots or cube roots, work backwards from square numbers and cube numbers. If you know that \(15^2 = 225\), then you also know that ...
