a) \(4.8^6.2.8^3\)
\(=2^2.\left(2^3\right)^6.2.\left(2^3\right)^3\)
\(=2^2.2^{18}.2.2^9\)
\(=2^{2+18+1+9}\)
\(=2^{30}\)
______
b) \(12^2.2.12^3.6\)
\(=12^2.12^3.2.6\)
\(=12^2.12^3.12\)
\(=12^{2+3+1}\)
\(=12^6\)
c) \(6^3.2.6^4.3\)
\(=6^3.6^4.2.3\)
\(=6^3.6^4.6\)
\(=6^{3+4+1}\)
\(6^8\)
a) \(4\cdot8^6\cdot2\cdot8^3\)
\(=2^2\cdot\left(2^3\right)^6\cdot2\cdot\left(2^3\right)^3\)
\(=2^2\cdot2^{18}\cdot2\cdot2^9\)
\(=2^{30}\)
b) \(12^2\cdot2\cdot12^3\cdot6\)
\(=12^2\cdot12\cdot12^3\)
\(=12^6\)
c) \(6^3\cdot2\cdot6^4\cdot3\)
\(=6^3\cdot6\cdot6^4\)
\(=6^8\)
Dòng cuối câu c phiền bạn thêm dấu " \(=\) " vô trước số \(6^8\) nhé.
