Question

[Tran Thi Loan]

\(\dfrac{45^{10}.5^{10}}{75^{10}}\)

\(\dfrac{(0,8)^5}{(0,4)^6}\)

\(\dfrac{2^{15}.9^4}{6^3.8^3}\)

\(\dfrac{8^{10}+4^{10}}{8^4+4^{11}}\)

Answer 1

[Lưu Hải Dương]

\(\dfrac{\text{45^{10^{ }}}.5^{10}}{75^{10}}=\dfrac{9^{10}.5^{10}.5^{10}}{5^{10}.5^{10}.3^{10}}=\dfrac{9^{10}}{3^{10}}=3^{10}\)

Answer 2

[Lưu Hải Dương]

\(\dfrac{\left(0,8\right)^5}{\left(0,4\right)^6}=\dfrac{2^5.\left(0,4\right)^5}{\left(0,4\right)^6}=\dfrac{2^5}{0,4}=\dfrac{32}{0,4}=80\)
