In the expression:(adsbygoogle = window.adsbygoogle || []).push({});

ksp = (3.42 x 10^-7) (6.84 x 10^-7)^2

= 1.6 x 10^-19

I don't understand how the final answer is found. Can someone show me a step by step? I'm attempting to understand how to do these types of questions! Any help is greatly appreciated!
