Question

Viết kết quả mỗi phép tính sau dưới dạng một lũy thừa:

a) 3⁴.3⁵;               16.2⁹;                             16.32;

b) 12⁸:12;             243:3⁴                            10⁹:10 000;

c) 4.8⁶.2.8³          12².2.12³.6;                    6³.2.6⁴.3.

Answer 1

a. \(3^4.3^5=3^9\)

\(16.2^9=2^4.2^9=2^{13}\)

\(16.32=2^4.2^5=2^9\)

b. \(12^8.12=12^9\)

\(243:3^4=3^5:3^4=3\)

\(10^9:10000=10^9:10^4=10^5\)

c. \(4.8^6.2.8^3=2^2.2^{18}.2.2^9=2^{30}\)

\(12^2.2.12^3.6=12^2.12.12^3=12^6\)

\(6^3.2.6^4.3=6^3.6.6^4=6^8\)
