5.) Irrational

Step-by-step explanation:

PRINCIPAL ROOT: RATIONAL OR IRRATIONAL

• The square root of a number n is any number s such that .
• Every positive number has two square roots, the positive and the negative. The square root is represented by the symbol . It is assumed that this is the positive square root of x. To show both the positive and negative values, you can use the symbol ±, read “plus or minus.”
• There are two categories of real numbers: rational and irrational. A square root that is not a perfect square is called an irrational number. Because the decimal does not end (non-terminating) and does not repeat a pattern (non-repeating), these numbers cannot be expressed as fractions. Despite the fact that irrational square roots cannot be represented as fractions, they may be stated exactly without the use of a calculator.
• The principal root is the positive number root.

Determine if the principal root is Rational or Irrational.

1.) = Irrational

2.) = Rational, the cube root is 5.

3.) = Rational, the 4th root is 7.

4.) = Irrational

5.) = Irrational
