Question

thực hiện phép tính:

\(\frac{2^7.9^2}{3^3.2^5}\)

Answer 1

\(\frac{2^7.9^2}{3^3.2^5}=\frac{2^7.3^4}{3^3.2^5}=\frac{2^2.3}{1.1}=12\)

Answer 2

\(\frac{2^7.9^2}{3^3.2^5}\)

\(=\frac{2^{5+2}.\left(3^2\right)^2}{3^3.2^5}\)

\(=\frac{2^5.2^2.3^4}{3^3.2^5}\)

\(=2^2.3\)

\(=4.3\)

\(=12\)

^_^

Answer 3

\(\frac{2^7\cdot9^2}{3^3\cdot2^5}\)

⇒\(\frac{2^7\cdot\left(3^2\right)^2}{3^3\cdot2^5}\)

⇒\(\frac{2^7\cdot3^4}{3^3\cdot2^5}\)

⇒\(2^2\cdot2\)

⇒\(4\cdot2\)

➩\(8\)
