Step-by-step explanation:

 \frac{ {2}^{x + 1}  +  {2}^{x} }{ {2}^{x + 1}  -  {2}^{x} }  \\  \\  =  \frac{ {2}^{x}  \times  {2}^{1}  +  {2}^{x} }{ {2}^{x}  \times  {2}^{1}  -  {2}^{x} }  \\  \\  =  \frac{ {2}^{x}( {2}^{1}   + 1)}{ {2}^{x} ( {2}^{1} - 1) }  \\  \\  =  \frac{2 + 1}{2 - 1}  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \\  \\  =  \frac{3}{1}  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \\  \\  = 3 \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \\  \\  \\ using \: formula \:  \:  \:  {x}^{m}  \times  {x}^{n }  =  {x}^{ m + n}
