Question

So sánh:

64⁸ và 16¹²

Answer 1

Ta có

\(64^8=\left(2^6\right)^8=2^{48}\)

\(16^{12}=\left(2^4\right)^{12}=2^{48}\)

\(\Rightarrow64^8=16^{12}\)

Answer 2

Ta có:64⁸=(4³)⁸=4²⁴

         16¹²=(4²)¹²=4²⁴

Vì 4=4 nên 4²⁴=4²⁴

hay 64⁸=16¹²

Vậy 64⁸=16¹²

Answer 3

Ta có:

64⁸=(2⁶)⁸=2⁴⁸

16¹²=(2⁴)¹²=2⁴⁸
