Since KOH is a strong base, it totally dissociates, and thus the concentration of hydroxide ions in solution equals to the concentration of the KOH.
0.70M KOH
note that:
[H+][OH-]= 1.0 x 10^-14
so,
[H+]= 1.0x10^-14 / [0.70M] = ______[H+]
since pH = -log[H+]
plug in the [H+] you found above into the equation for pH.
