pOH value is to measure how basic or acidic a solution is.
pOH is calculated using the following equation 
pOH  = -log [OH⁻]
since pOH is known, to calculate hydroxide ion concentration we need to find antilog
[OH⁻] = antilog (-4.65)
antilog can be calculated as follows
[OH⁻]  = 10^(-4.65) 
hydroxide ion concentration = 2.24 x 10⁻⁵ M

Answer:

What is the hydronium ion concentration in a solution of HCl that has a pH of 4.65?

2.24 × 10n M

n = -5

What is the hydroxide ion concentration in a solution of NH3 with a pOH of 4.65?

2.24 × 10n M

n = -5
