WebThe Simplifying Radicals with Imaginary Numbers Scavenger Hunt Game gets students up and moving around while practicing math. In this game, students use the answer to one … WebSince i is a radical, you should simplify further by rationalizing the denominator. Since the denominator is just one term, you don’t need to think about complex conjugates. Just multiply by 1 in the form and simplify. (Remember, the product of two imaginary numbers is real, so the denominator is real.) Answer. 56 ÷ −7i = 8i
WebA complex number is expressed in standard form when written a + bi where a is the real part and bi is the imaginary part. For example, [latex]5+2i[/latex] is a complex number. So, too, is [latex]3+4i\sqrt{3}[/latex]. Imaginary numbers are distinguished from real numbers because a squared imaginary number produces a negative real 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.
