Question

Rút gọn phân số:

\(\frac{2^3.3^3.5^3.7.8}{3.2^4.5^3.14}\)

Answer 1

\(\frac{2^3.3^3.5^3.7.8}{3.2^4.5^3.14}=\frac{2^3.3^3.5^3.7.2^3}{3.2^4.5^3.2.7}\)

\(=\frac{2^6.3^3.5^3.7}{2^5.3.5^3.7}=\frac{2.3^2.1.1}{1.1.1.1}=2.3^2\)

\(=2.9=18\)

Answer 2

\(\frac{2^3.3^3.5^3.7.8}{3.2^4.5^3.14}=\frac{1.3^2.1.1.8}{1.2.1.2}=\frac{3.3.4}{2.1}=\frac{3.3.2}{1}=18\)

Answer 3

\(...=\frac{2^6.3^3.5^3.7}{2.^53.5^3.7}=18\)

Answer 4

\(\frac{2^3.3^3.5^3.7.8}{3.2^4.5^3.14}\)= \(\frac{2.2.2.3.3.3.5.5.5.7.2.2.2}{3.2.2.2.2.5.5.5.7.2}\)=  \(\frac{3.3.2}{1}\)= \(\frac{18}{1}\)= 18
