3^{x} + 3^{x + 2} = 30

Factor

3^{x} + 3^{x + 2} : 10 \cdot 3^{x}

10 \cdot 3^{x} = 30

Divide both sides by

10

3^{x} = 3

x = 1

Popular Examples

5^{3x-2}=25^{2x+1}

5^{3 x - 2} = 2 5^{2 x + 1}

e^{-x^2-y^2}y(1-2x^2)=0

e^{- x^{2} - y^{2}} y (1 - 2 x^{2}) = 0

5^{8 x + 5} = 2

4^3+4^3+4^3+4^3=64^x

4^{3} + 4^{3} + 4^{3} + 4^{3} = 6 4^{x}

2^{x+1}=5^{2x-1}

2^{x + 1} = 5^{2 x - 1}
