Question

A=2023²⁰²³/2023²⁰²⁴        B=2023²⁰²²/2023²⁰²³

^{so sánh A và B}

Answer 1

Ta có : \(A\text{=}\dfrac{2023^{2023}}{2023^{2024}}\text{=}\dfrac{1}{2023}\)

và \(B\text{=}\dfrac{2023^{2022}}{2023^{2023}}\text{=}\dfrac{1}{2023}\)

\(\Rightarrow A\text{=}B\)

Answer 2

Ta có :

A=\(\dfrac{2023^{2023}}{2023^{2024}}\)=\(\dfrac{2023^{2022}.2023}{2023^{2023}.2023}\)=\(\dfrac{2023^{2022}}{2023^{2023}}\)

Mà B=\(\dfrac{2023^{2023}}{2023^{2024}}\)

Vậy A=B
