\(D=6+6^2+6^3+...+6^{100}\)

\(6D=6\left(6+6^2+6^3+...+6^{100}\right)\)

\(6D=6^2+6^3+6^4+...+6^{101}\)

\(6D-D=\left(6^2+6^3+6^4+...+6^{101}\right)-\left(6+6^2+6^3+...+6^{100}\right)\)

\(5D=6^{101}-6\)

\(D=\dfrac{6^{101}-6}{5}\)

Vậy \(D=\dfrac{6^{101}-6}{5}\)

Ta có: \(150\%=\dfrac{150}{100}=\dfrac{3}{2}\)
