Answer:

x = \frac{log\sqrt{-1/6}}{log2}

Step-by-step explanation:

Given the expression

2^{2x}+3-7(2^{2x}+1)+3=0

Let P=2^x

Substituting into the expression, we will have:

P^2+3-7(P^2+1)+3=0\\Expand\\P^2+3-7P^2-7+3=0\\-6P^2-1=0\\6P^2=-1\\p^2=-1/6\\P=\sqrt{-1/6}

Since:

P=2^x\\2^x=\sqrt{-1/6}\\xlog2=log(\sqrt{-1/6}) \\x = \frac{log\sqrt{-1/6}}{log2}
