The thing that I learned this week are Simplifying Radical Expressions, Adding and Subtracting Radical Expressions, Multiplying and Dividing Radical Expression.
radicand is consists of index, radicand and coffcient .
And Roots include the Square Roots, Cube Roots and other Roots.
If √ssasdasdasda16=4 ,So it’s the perfect Square, because 4 is an integer.
If ³√8=2, So it’s the perfect cube.
And √x2=|x| , to simplify radicals with index 2.
All square numbers are greater than or equal to 0,so the expression √x has a real number value only when x is greater than or euqal to 0. √x is defined for X∈R, x>=0
