You can solve it without calculator
where PH=10
[H+].[OH-]=10^-14
10^-10.[OH]=10^-14
Divide both side by 10^-10
[OH]=10^-14/10^-10
[OH]= 10^-14+10
[OH]=10^-4mol/dm3

PH+POH =14
POH=14-10
POH=4
using this formula ,calculate it from the answer the one that will give you 4
p-n/7
1*10^-4
4-1/7
4-0.14
=3.68 ~~ 4
