Question

giải bài toán theo 2 cách

(5 ​²⁰⁰¹ - 5^{2000 ) :} 5²⁰⁰⁰ =

 

Answer 1

\(\left(5^{2001}-5^{2000}\right):5^{2000}=5^{2001}:5^{2000}-5^{2000}:5^{2000}=5-1=4\)

Answer 2

Cách 1:

\(\left(5^{2001}-5^{2000}\right)\div5^{2000}\)

\(=5^{2001}\div5^{2000}-5^{2000}\div5^{2000}\)

\(=5-1=4\)

Cách 2:

\(\left(5^{2001}-5^{2000}\right)\div5^{2000}\)

\(=5^{2000}\cdot\left(5-1\right)\div5^{2000}\)

\(=4\)
