2^{x+1}+2^x=12

Solution

2^{x + 1} + 2^{x} = 12

Solution

x = 2

Solution steps

2^{x + 1} + 2^{x} = 12

Factor

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

3 \cdot 2^{x} = 12

Divide both sides by

3

2^{x} = 4

Apply exponent rules

x = 2

Popular Examples

(16^8)^x=(2^2)^{35}

(1 6^{8})^{x} = (2^{2})^{35}

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

2^{x^{2} - 1} = 0

9^{x + 2} = 27

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

lo g_{2} (2 5^{x} + 3 - 1) = 2 + lo g_{2} (5^{x} + 3 + 1)
