You can put this solution on YOUR website!
Exactly as shown as text, the expression is b%5E%28-1%29+%2B+d%5E%28-1%29+%2F+%28b%29%5E%28-1%29.

Any number raised to negative one power works this way:
x%5E-1=1%2Fx.

Yours becomes
1%2Fb%2Bb%2Fd
%28d%2Fd%29%281%2Fb%29%2B%28b%2Fb%29%28b%2Fd%29
%28d%2Bb%2Ab%29%2F%28bd%29
highlight%28%28d%2Bb%5E2%29%2F%28bd%29%29
