Radical 567x2y4z2 with a 4 index
+2446 ManuelBautista2019, I am certain that the preceding answerers have misinterpreted the question.
You mean 4√567x2y4z2. Notice that this expression has a radical with an index of 4!
4√567x2y4z24√34∗7∗x2∗y4∗z23|y|4√7x2z2
This radical is now in simplest form. And, yes, the absolute value bars around y is deliberate and intentional.
y^4 will always be positive--whether or not y is positive or negative. Taking the 4th root of a number implies the principal root, or the positive answer, so y cannot be negative. We account for this by adding absolute value bars.
