Question 6. All right recruit! You’ve done well. Now the only thing you need to do now would be to finalize one more expression. The architect originally wanted there to be a giant aquarium in the back, but a problem arose and now the space there needs to be expanded. The expression (x²y³/4x³y²)³ would be the best way to model the final expression. If you could solve this then you’ll be done for the day. So bud, what is the simplified expression of (x²y³/4x³y²)³?

• x^-2y²/4

• y²/4x²

• y²/16x²

• y²/4x¹

Simplify the expression:

 $\frac{2^8z^{10}}{2^6z^3}$  

•  $2^{14}z^{13}$  
  

•  $\frac{2^2}{z^7}$  
  

•  $\frac{2^{14}}{z^7}$  
  

•  $2^2z^7$  
  

Simplify:   $\left(\frac{2a^{-3}b^4}{5a^7c^3}\right)^{-1}$  

•  $\frac{5c^3}{2a^{10}b^4}$  

•  $\frac{2a^4b^4}{5c^3}$  

•  $\frac{5c^3}{2a^4b^4}$  

•  $\frac{5a^{10}c^3}{2b^4}$
