Ta có:
\(A=8^{2017}.25^{3024}\)
\(\Rightarrow A=\left(2^3\right)^{2017}.\left(5^2\right)^{3024}\)
\(\Rightarrow A=2^{6051}.5^{6048}\)
\(\Rightarrow A=2^{6048}.2^3.5^{6048}\)
\(\Rightarrow A=\left(2.5\right)^{6048}.2^3\)
\(\Rightarrow A=10^{6048}.8\)
Ta có: \(10^{6048}\) có 6048 chữ số
=> 106048.8 có 80.................................00
( 6048 chữ số)
