Rearrange the formula to find the underlined variables.

v = hvh

Simplifying the above equation:

v = h × v × h

Taking the RHS 'v' to LHS

⇒ v ÷ v = h × h

⇒ 1 = h × h

⇒ 1 =

⇒ h = √1

⇒ h =

So h can have the values +1 or -1.

Putting h = +1 in the equation,

v = (+1) × v × (+1)

⇒ v = v

Hence, v can take any integer value.

Putting h = -1 in the equation, when h = 1.

v = (-1) × v × (-1)

⇒ v = v

Hence, v can take any integer value when h = -1.

Hence, as long as h is either +1 or -1, v can take any integer value.
