Question

Tính:

\(\dfrac{8^3.5^4}{4^5.125}\)

Answer 1

\(\dfrac{8^3.5^4}{4^5.125}=\dfrac{2^9.5^4}{2^{10}.5^3}=\dfrac{5}{2}\)

Answer 2

\(\dfrac{8^3\cdot5^4}{4^5\cdot125}=\dfrac{2^9}{2^{10}}\cdot5=\dfrac{5}{2}\)

Answer 3

\(\dfrac{8^3.5^4}{4^5.125}=\dfrac{\left(4^2\right)^3.5^4}{4^5.5^3}=\dfrac{4^5.5^4}{4^5.5^3}=5\)
