Numerical expressions

Evaluate: 

 $\left(\frac{2}{3}\right)^3\left(\frac{2}{3}\right)^{-7}$  

•  $\left(\frac{2}{3}\right)^{-21}$  

•  $\frac{81}{16}$  

•  $\left(\frac{2}{3}\right)^{10}$  

•  $\left(\frac{3}{2}\right)^{-4}$  

Solve:
6^x + 5 = 221

• x = 36
• x = 216
• x = 3
• x = 2

Answer explanation

 $\left(-4\right)^{-2}$  

 $=\frac{1}{\left(-4\right)^2}$  

  $=\frac{1}{\left(-4\right)\cdot\left(-4\right)}$  
 $=\frac{1}{16}$
