Answer 1

`@` `\text {Ans}`

`\downarrow`

\(3^2\cdot2^5\cdot\left(\dfrac{2}{3}\right)^2\)

`=`\(\left(3\cdot\dfrac{2}{3}\right)^2\cdot2^5\)

`=`\(2^2\cdot2^5=2^7\)

Answer 2

\(3^2\cdot2^5\cdot\left(\dfrac{2}{3}\right)^2\)

\(=2^5\cdot\left(3\cdot\dfrac{2}{3}\right)^2\)

\(=2^5\cdot\left(\dfrac{3\cdot2}{3}\right)^2\)

\(=2^5\cdot2^2\)

\(=2^{2+5}\)

\(=2^5\)
