--------------
You don't solve it.  Equations are solved, this is not an equation.
------------------
(5 x 10 to the 5th) to the negative 2nd
{{{(5*10^5)^-2}}}
= {{{1/(5*10^5)^2}}}
= = {{{1/(25*10^10)}}}
= {{{(1/25)*(1/10^10)}}}
= {{{0.04*10^-10}}}
= {{{4*10^-12}}}
Or 4E-12

PS  Use the asterisk * for multiply.
x is used for other things.
