Answer :
Two more whole numbers 9 and 81
Step-by-step explanation:
[tex]3^{20} = 3,486,784,401 \\ \\ ( {3}^{2} )^{10} = 3,486,784,401 \\ \\ \huge \red{ \boxed{{9}^{10} = 3,486,784,401}} \\ \\ ( {9}^{2} )^{5} = 3,486,784,401 \\ \\ \huge \red{ \boxed{{81}^{5} = 3,486,784,401 }}\\ \\ [/tex]
So, two more whole numbers 9 and 81 can be raised to a power to get 3,486,784, 401.
