4^x+4^x= 1/2

4^{x} + 4^{x} = \frac{1}{2}

x = - 1

Solution steps

4^{x} + 4^{x} = \frac{1}{2}

Add similar elements:

4^{x} + 4^{x} = 2 \cdot 4^{x}

2 \cdot 4^{x} = \frac{1}{2}

Divide both sides by

2

4^{x} = \frac{1}{4}

Apply exponent rules

x = - 1

2 e^{2 x} + 12 = 11 e^{x}

0 = e^{\frac{1}{x}}

2^{x + 2} = 256

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

1000000 = 100 e^{4.6052 T}
