WebMay 24, 2024 · Definition 4.8.3. A complex number is of the form a + bi, where a and b are real numbers. Figure 8.8.1. A complex number is in standard form when written as a + bi, where a and b are real numbers. If b = 0, then a + bi becomes a + 0 ⋅ i = a, and is a real number. If b ≠ 0, then a + bi is an imaginary number. WebSolution: Step 1: In this example, we have a cubic root, as the index is 3. We have the number 8 inside the cube root, but we know that 8 3 = 2, so we can write 2 outside of the radical ⇒ 2 3. We also have 2 variables x and y. However, both variables appear in the numerator and denominator of the fraction. WebSimplify by multiplication of all variables both inside and outside the radical. Example 1. Simplify: √252. Solution. Find the prime factors of the number inside the radical. 252 = 2 x … phlebotomist specimen processor
