The authors consider an even order advanced type dynamic equation with mixed nonlinearities as \[ \bigl[r(t)\varPhi_\alpha\bigl(x^{\Delta^{n-1}}(t)\bigr)\bigr]^\Delta+p(t)\varPhi_\alpha\bigl(x\bigl(\delta(t)\bigr)\bigr)+\sum\limits_{i=1}^kp_i(t)\varPhi_{\alpha_i}\bigl(x\bigl(\delta(t)\bigr)\bigr)=0 \quad (1) \] on an arbitrary time scale \(\mathbb T\) with \(\sup T=\infty\). Moreover, they assume that the following properties are satisfied:
i) \(n\geq 2\) is even, \(\alpha_{1}>\dots>\alpha_{m}>\alpha>\alpha_{m+1}>\dots>\alpha_{k}>0\),
ii) \(r,p,p_{i}\in C_{rd}([t_0,\infty)_{T},(0,\infty)), i=1,\dots,k\) and \(\int_{t0}^{\infty}r^{-1/\alpha}(t)\Delta t=\infty\),
iii) \(\varPhi_{\ast}(u)=|u|^{\ast-1}u, \delta\in C_{rd}(T,T)\) and \(\delta(t)\geq t, t\in [t_0,\infty)_{T}\).
Using Hardy-Littlewood-Polya inequality, arithmetic-geometric mean inequality, introducing parameter functions and developing a generalized Riccati technique, the authors obtain some oscillation criteria for (1).
