\(\frac{2^7.9^2}{3^3.2^5}=\frac{2^7.3^4}{3^3.2^5}=\frac{2^2.3}{1.1}=12\)
\(\frac{2^7.9^2}{3^3.2^5}\)
\(=\frac{2^{5+2}.\left(3^2\right)^2}{3^3.2^5}\)
\(=\frac{2^5.2^2.3^4}{3^3.2^5}\)
\(=2^2.3\)
\(=4.3\)
\(=12\)
^_^
\(\frac{2^7\cdot9^2}{3^3\cdot2^5}\)
⇒\(\frac{2^7\cdot\left(3^2\right)^2}{3^3\cdot2^5}\)
⇒\(\frac{2^7\cdot3^4}{3^3\cdot2^5}\)
⇒\(2^2\cdot2\)
⇒\(4\cdot2\)
➩\(8\)
