5*2^x+2^{x+2}=18

Solution

5 \cdot 2^{x} + 2^{x + 2} = 18

Solution

x = 1

Solution steps

5 \cdot 2^{x} + 2^{x + 2} = 18

Factor

5 \cdot 2^{x} + 2^{x + 2} : 9 \cdot 2^{x}

9 \cdot 2^{x} = 18

Divide both sides by

9

2^{x} = 2

Apply exponent rules

x = 1

x, e^{x} = \frac{y}{y - 2}

8^{2x-1}= 1/(2^{x-5)}

8^{2 x - 1} = \frac{1}{2 ^{x - 5}}

3^{2x-8}=5^{2x-8}

3^{2 x - 8} = 5^{2 x - 8}

4^x(8^{2x-1})=64

4^{x} (8^{2 x - 1}) = 64

4^{2 x} = 8^{x + 3}
