    you can simply do it by the easier method- write 3 as = 3/1 * 7 = 21/7 and 4 as = 4/1 * 7 = 28/7 Now we have succesfully made the denominator same, hence the 6 rational numbers between 3 and 4 would be.... 22/7,23/7,24/7,25/7,26/7 hope it helped you :)

    yes, -25 is a rational number because, we can write it in the form of p/q = -25/2, -25/4,-25/10 and so on.....(any number which can be written in the form of p/q where q is not equal to 0 is called a rational number) hope it helped you :)

    Preeti Dabral 3 years, 3 months ago

    Given that

    x = 2 + √3

    1/x = 1/2 + √3

    = 1 × (2 - √3)/(2 + √3) (2 - √3)

    = (2 - √3)/(2^2 - √3^2)

    = (2 - √3)/4 - 3

    = (2 - √3)

    Therefore ,

    x^2 = (2 + √3)

    = (2)^2 + (√3)^2 + 2 × 2 × √3

    = 4 + 3 + 4√3

    = 7 + 4√3

    1/x^2 = (2 - √3)^2

    = (2)^2 + (√3)^2 - 2 × 2 × √3

    = 4 + 3 - 4√3

    = 7 - 4√3

    x^2 + 1/x^2

    = (7 + 4√3) + (7 - 4√3)

    = 7 + 4√3 + 7 - 4√3

    = 7 + 7 + 4√3 - 4√3

    = 14
