Question

What mathematical can be put between 5 and 9 to get a value bigger than 5 and smaller than nine​

Answer 1

Answer:

This question was originally asked as “between 6 and 9” and then changed to “between 5 and 9”, so some answers address the former and some the latter. The following suggestions are written with “5” but most of them work equally well with “6”.

5.9 or 5,9 (decimal mark)

If this question originated as a quiz or classroom challenge question, this answer (the decimal mark) is probably the one expected, and it is the one which most closely meets the requirement of a “mathematical symbol”. However, there is a wide range of alternatives:

59–√4≈8.6603, or indeed 59–√5, or 59–√6, etc: any order of root from 4 up will work here.

5log59≈6.8261, or indeed 5log69, 5log69 or 5log69 will also work here (logarithm)

5coth9≈5.0000001523 (hyperbolic cosine)

5arcsec9≈7.2973 (arcsecant)

5arctan9≈7.3007 (arctangent)

5⊕9=7 where we have defined ⊕:R×R→R such that a⊕b↦12(a+b) ∀a,b∈R.

5gd9≈7.8527 (Gudermannian function)

5Si9≈8.3252 (sine integral)

5ζ9≈5.01004 (Riemann zeta function)

5C109≈5.55555550955 (Champernowne constant)
