Question

so sành 2 ^90 và 5^36

Answer 1

Ta có : \(2^{90}=\left(2^{10}\right)^9=1024^9\)

\(5^{36}=\left(5^4\right)^9=625^9\)

Ta thấy : \(1024^9>625^9\Rightarrow2^{90}>5^{36}\)

Answer 2

2^90= (2^10)^9 = 1024 ^9

5^36 = (5^4)^9 = 625^9

ta thấy 1024^9 > 625^9 nên 2^90>5^36

Answer 3

\(2^{90}=2^{10.9}=\left(2^{10}\right)^9=1024^9.\)

\(5^{36}=5^{4.9}=\left(5^4\right)^9=625^9.\)

                Vì\(1024>625\)

                          \(\Rightarrow625^9< 1024^9\)

                          Hay \(2^{90}>5^{36}.\)

Answer 4

2^90 = ( 2^10 )^9 = 1024^9

5^36 = ( 5^4 )^9 = 625^9

Vì 1024 > 625 nên 1024^9 > 625^9 hay 2^90 > 5^36

Answer 5

\(2^{90}=\left(2^{10}\right)^9=1024^9\)

\(5^{36}=\left(5^4\right)^9=625^9\)

Vì 1024 > 625

nên bạn tự kết luận

Answer 6

Ta có:

\(2^{90}=\left(2^{10}\right)^9=1024^9\)

\(5^{36}=\left(5^4\right)^9=625^9\)

Vì \(1024^9>625^9\Rightarrow2^{90}>5^{36}\)

Vậy 2⁹⁰ > 5³⁶ .
