Question

tìm số nguyên n biết (-36)^1000:(9)^1000=2^n trả lời:x=

Answer 1

(-36)^1000:(-9)^1000=2^n

[(-36):9]^1000=2^n

  4^1000=2^n

  2^(2.1000)=2^n

 2^2000=2^n

 vậy n = 2000

Answer 2

\(\left(-36\right)^{1000}:9^{1000}=2^n\)

\(36^{1000}:9^{1000}=2^n\)

\(\left(36:9\right)^{1000}=2^n\)

\(4^{1000}=2^n\)

\(\left(2^2\right)^{1000}=2^n\)

\(2^{2000}=2^n\)

\(\Rightarrow n=2000\)
