Which expressions represent rational numbers? Check all that apply...

Answer is in the steps read carefully.

Step-by-step explanation:

  does not represent a rational number because the square root of 6 is not a perfect square.

   This represents a rational number because the square root of 64 is a perfect square which is 8  and if added to a fraction you will get a rational number.

  represents  a rational number because they are both a perfect square. The square root of 16 is 4 and the square root of 169  is  13.

  represents a rational number because since 17.43 repeating can be expressed as a fraction, and the square root of 49  is a perfect square, if added together they will generate a rational number.

    Does not represents a rational number because the square root of  44 is not a perfect  square  and when you add an irrational number and an rational number then you will get an irrational number.

hello :

by applying the distributive property :

6 × 4.3 = 6 × ( 4 + 0.3 )

            =   (6 ×   4) + (6 ×   0.3)

            = 24 + 1.8

6 × 4.3 = 25.8
