\(9\cdot9\cdot9\cdot9\cdot3\cdot3=9\cdot9\cdot9\cdot9\cdot9=9^5\)

\(4\cdot4\cdot4\cdot4\cdot4\cdot4\cdot4\cdot4\cdot4\cdot2^2=4\cdot4\cdot4\cdot4\cdot4\cdot4\cdot4\cdot4\cdot4\cdot4=4^{10}\)

a) \(8^7\cdot8^3=8^{7+3}=8^{10}\)

b) \(4^4\cdot4^7\cdot4=4^{4+7+1}=4^{12}\)

c) \(2^8\cdot8\cdot2^6=2^8\cdot2^3\cdot2^6=2^{8+3+6}=2^{17}\)

d) \(a\cdot a^2\cdot a^3\cdot a^4=a^{1+2+3+4}=a^{10}\)

\(2a^5b^4c\left(-4a^2c^9\right)\left(-ab^2\right)\) \(=8a^8b^6c^{10}\)

(Nguyên tử trong bài là Mg)

\(x:\dfrac{2}{3}=\dfrac{3}{5}\)

\(x=\dfrac{3}{5}\times\dfrac{2}{3}\)

\(x=\dfrac{6}{15}=\dfrac{2}{5}\)

Đáp án C
