Question

so sanh:

a) 3²⁰⁰ va 2²⁰⁰

b) 9¹² va 26⁸

Answer 1

a) Ta có:3>2

\(\Rightarrow3^{200}>2^{200}\)

b) Ta có:\(9^{12}=\left(9^3\right)^4=729^4\)

\(26^8=\left(26^2\right)^4=676^4\)

Vì: 729>676

\(\Rightarrow729^4>676^4\)

Hay: \(9^{12}>26^8\)

Answer 2

a,3²⁰⁰>2²⁰⁰

b,9¹²=(3²)¹²=3²⁴

26⁸=(13.2)⁸

Answer 3

 a) 3²⁰⁰=3^2x100=(3²)¹⁰⁰=9¹⁰⁰

  2³⁰⁰=2^3x100=(2³)¹⁰⁰=8¹⁰⁰

Vì 9¹⁰⁰  >   8¹⁰⁰

==>3²⁰⁰  >  2³⁰⁰

b) 9¹²=3^2x12=3²⁴=(3³)⁸=27⁸

Vì 27⁸  > 26⁸

==> 9¹² > 26⁸
