Question

2^2:2^2x =8:1 find the answer ​

Answer 1

Answer:

–1/2

Step-by-step explanation:

2^2 : 2^2x = 8 : 1

$= > \frac{2 {}^{2} }{2 {}^{2x} } = \frac{8}{1}$

$= > {2}^{2} = 8 \times {2}^{2x} \\ = > {2}^{2 - 2x} = 2 {}^{3} \\ = > 2 - 2x = 3 \\ = > 2 - 3 = 2x \\ = > - 1 = 2x \\ = > 2x = - 1 \\ = > x = \frac{ - 1}{2}$
