Question

Thuc hien phep tinh :

\(\frac{3^8.16^2}{12^4.8^3}\)

Answer 1

3⁸.16²/12⁴.8³

= 3⁸.(2⁴)²/(2².3)⁴.(2³)³

= 3⁸.2⁸/2⁸.3⁴.2⁹

=3⁴/2⁹

=81/512

Answer 2

\(\frac{3^8\cdot16^2}{12^4\cdot8^3}\)

\(=\frac{3^8\cdot2^8}{3^4\cdot2^8\cdot2^9}\)

\(=\frac{81}{512}\)

Answer 3

\(=\frac{3^8.\left(2^4\right)^2}{\left(3.4\right)^4.\left(2^3\right)^3}=\frac{3^8.2^8}{3^4.\left(2^2\right)^4.2^9}=\frac{3^4}{2^9}=\frac{81}{512}\)
