Which table best classifies the following numbers as rational and irrational?

negative 6 over 5., square root of 5., 3.5, 0 point 5 bar., square root of 4.

rational square root of 5.
irrational negative 6 over 5., 3.5, 0 point 5 bar., square root of 4.

rational square root of 4., square root of 5.
irrational negative 6 over 5., 3.5, 0 point 5 bar.

rational negative 6 over 5., 3.5, 0 point 5 bar.
irrational square root of 4., square root of 5.

rational negative 6 over 5., 3.5, 0 point 5 bar., square root of 4.
irrational square root of 5.

Rational: negative 6 over 5, 3.5, 0 point 5 bar , square root of 4.

Irrational: square root of 5.

Step-by-step explanation:

We know that a rational number is a number which can be expressed in the form of ; where p belongs to integer and q belongs to the set of natural numbers.

so here the set of rational number is:

negative 6 over 5 , 3.5 as it is equal to 7 over 2 , 0  point 5 bar, and square root of 4 as it is equal to +2 or -2.

and the irrational number is:

square root of 5.

step-by-step explanation:

then i will answer

since your problem is x^4 = 81, what you have to undeo is the "to the fourth power" part.

the inverse (opposite operation) of "to the fourth power" is "to the fourth root".

  (x^4) ^ ¼   = 81 ^ ¼  

  81 = 3^4     so (3 ^ 4) ^ ¼   =   3 ^ 1   = 3

by hand: (3 ^ 4) ^ ¼   =   3 ^ (4 x ¼) = 3 ^ 1   = 3   (when you take a power to a power, multiply the exponents.)

or, do it by calculator. one way of finding the fourth root is to use ^ (1/4)
