[tex] \bf {4}^{20} = ( {2}^{2} )^{20} = {2}^{2 \cdot 20} = {2}^{40} [/tex]
[tex] \bf {8}^{10} = ( {2}^{3} )^{10} = {2}^{3 \cdot 10} = {2}^{30} [/tex]

[tex] \bf {4}^{20} \cdot {2}^{40} \cdot {8}^{10} = \\ \\ \bf = {2}^{40} \cdot {2}^{40} \cdot {2}^{30} = \\ \\ \bf = {2}^{40 + 40 + 30} = \boxed{ {2}^{110} } [/tex]
