Answer:


\frac{{3}^(3) * {x}^(2) - 25}{5}


\frac{3 * 3 * 3 * ( {0.6)}^(2) - 25}{5}


(3 * 3 * 3 * 0.6 * 0.6 - 25)/(5)


(27 * 0.36 - 25)/(5)


\frac{9.72 - \cancel{25} \: 5}{ \cancel5}


9.72 - 5


4.72

Hey there!

3^3 * x^2 - 25 / 5

= 3^3 * 0.6^2 - 25 / 5

= 3 * 3 * 3 * 0.6 * 0.6 - 25 / 5

= 9 * 3 * 0.6 * 0.6 - 25 / 5

= 27 * 0.36 - 25 / 5

= 9.72 - 25 / 5

= 9.72 - 5

= 4.72


Therefore, your answer is: 4.72


Good luck on your assignment & enjoy your day!
