Question

viết tích \(25^6.8^4\)​​ dưới dạng lũy thừa cơ số 10

Answer 1

\(25^6\cdot8^4\)

\(=\left(5^2\right)^6\cdot\left(2^3\right)^4\)

\(=5^{2\cdot6}\cdot2^{3\cdot4}\)

\(=5^{12}\cdot2^{12}\)

\(=\left(5\cdot2\right)^{12}\)

\(=10^{12}\)

Answer 2

\(25^6.8^4\)

\(=\left(5^2\right)^6.\left(2^3\right)^4\)

\(=5^{2.6}.2^{3.4}\)

\(=5^{12}.2^{12}\)

\(=\left(5.2\right)^{12}\)

\(=10^{12}\)
