$3^{x}$- $3^{x-1}$- $3^{x-2}$
You asked:
Evaluate the expression: \({3}^{x} - {3}^{x - 1} - {3}^{x - 2}\)
MathBot Answer:
Evaluated
\(\displaystyle {3}^{x} - {3}^{x - 1} - {3}^{x - 2} = 3^{x} - 3^{x - 2} - 3^{x - 1} \)
Expanded
\[{3}^{x} - {3}^{x - 1} - {3}^{x - 2} = \frac{5 \cdot 3^{x}}{9}\]
Factored
\[{3}^{x} - {3}^{x - 1} - {3}^{x - 2} = \frac{5 \cdot 3^{x}}{9}\]
