The value of constant variation is √16.
A mathematical constant is a significant integer that has a steady value and is specified by a precise definition.
relationship between two variables in mathematics that may be represented by an equation where the product of their products equals a constant
Inverse variation is y = k. 1/x
given y = √18
x = √2
So, √8 = k. 1/√2
So, the value of k = √16
We can conclude that the value of constant variation is √16
