\(VT=2^{30}+3^{20}+4^{30}\)
\(=\left(2^3\right)^{10}+\left(3^2\right)^{10}+\left(4^3\right)^{10}\)
\(=8^{10}+9^{10}+64^{10}\)
\(VP=3^{20}+6^{20}+8^{20}\)
\(=\left(3^2\right)^{10}+\left(6^2\right)^{10}+\left(2^3\right)^{20}\)
\(=9^{10}+36^{10}+8^{20}\)
\(=9^{10}+36^{10}+\left(8^2\right)^{10}\)
\(=9^{10}+36^{10}+64^{10}\)
\(\left\{{}\begin{matrix}9^{10}=9^{10}\\64^{10}=64^{10}\\36^{10}>9^{10}\end{matrix}\right.\)
\(\Rightarrow VT< VP\)
