3^x+3^{x+1}+3^{x+2}=351

3^{x} + 3^{x + 1} + 3^{x + 2} = 351

x = 3

Solution steps

3^{x} + 3^{x + 1} + 3^{x + 2} = 351

Factor

3^{x} + 3^{x + 1} + 3^{x + 2} : 13 \cdot 3^{x}

13 \cdot 3^{x} = 351

Divide both sides by

13

3^{x} = 27

Apply exponent rules

x = 3

e^{- 0.2 t} = 64

x^{x} = 1000

y, x = 1 0^{y}

(a^{- x})^{2} = a^{14}

4^{x} - 10 \cdot 4^{- x} = 3
