The symbol which correctly compares the numbers is <, i.e less than.
Given the expression is ∛27 = 21/5
Mathematicians refer to the process or method of comparing numbers as a way of figuring out if one number is less than, equal to, or higher than another one given their values.
first get the values of the numbers
∛27 = 3×3×3 = 27
hence we get it as 3
now for 21/5 = 4.2
hence the second value is greater than the first value and but as the expression says the first value is less than the second value.
Hence the correct expression is:
3<4.2
Therefore, the symbol which compares the correct form of expression is < that is less than.
