1/7 power 4-2x = root 7 find the value of x ​

Answer»

EXPLANATION:-

\frac{1}{{7}^{4 - 2x}} = \sqrt{7} = > {7}^{ - (4 - 2x)} = {7}^{ \frac{1}{2} } = >

{7}^{2x - 4} = {7}^{ \frac{1}{2}} = > 2x - 4 = \frac{1}{2} = >

4x - 8 = 1 = > 4x = 8 + 1 = 9 = >

4x = 9 = > x = \frac{9}{4}

HOPE it HELPS you.
