Answer 2

[FL.Han_]

Ta có:\(2^{36}\)và \(3^{27}\)

\(2^{36}=\left(2^4\right)^9=16^9\)

\(3^{27}=\left(3^3\right)^9=27^9\)

Vì \(16< 27\Rightarrow16^9< 27^9\)

Vậy....

b,\(9^{20}\)và \(9999^{10}\)

\(9^{20}=\left(9^2\right)^{10}=81^{10}\)

\(9999^{10}\)

Vì \(81< 9999\Rightarrow81^{10}< 9999^{10}\)

Vậy ...

c,\(54^4\)

\(21^{12}=\left(21^3\right)^4=9261^4\)

Vì \(54< 9261\Rightarrow54^4< 9261^4\)

Vậy...
