$\mathrm{P}_4 \mathrm{O}_{10}$ being a dehydrating agent removes a molecule of water and forms anhydride of $\mathrm{HNO}_3$. The reaction involved is given as
$$
4 \mathrm{HNO}_3+\mathrm{P}_4 \mathrm{H}_{10} \longrightarrow 4 \mathrm{HPO}_3+2 \mathrm{~N}_2 \mathrm{O}_5
$$
$\mathrm{N}_2 \mathrm{O}_5$ formed has two resonating structure given as :
$$
4 \mathrm{HNO}_3+\mathrm{P}_4 \mathrm{H}_{10} \longrightarrow 4 \mathrm{HPO}_3+2 \mathrm{~N}_2 \mathrm{O}_5
$$
$\mathrm{N}_2 \mathrm{O}_5$ formed has two resonating structure given as :
