Question

so sánh hai phân số sau : 16^2020 + 1 / 16^2021 + 1 và 16^2021 + 1 / 16^2022 + 1

Answer 1

1) \(16^{2020}+\dfrac{1}{16^{2021}}+1\)

\(=16^{2021}\div16^{2020}+1\)

\(=16+1\)

\(=17\)

2) \(16^{2021}+\dfrac{1}{16^{2022}}+1\)

\(=16^{2022}\div16^{2021}+1\)

\(=16+1\)

= 17

Vì 17=17 nên \(16^{2020}+\dfrac{1}{16^{2021}}+1=16^{2021}+\dfrac{1}{16^{2022}}+1\)
