Step-by-step explanation:
If Logx<span> (1 / 8) = - 3 / 2, then x is equal to </span>
Solution
Rewrite the logarithmic equations using exponential equation
x- 3 / 2<span> = 1 / 8 </span>
The above equation may be rewritten as
x<span> - 3 / 2</span><span> = 1 / 2</span>3<span> = 2</span>-3
(√x)-3<span> = 2</span>-3
The above equation gives
<span>√x = 2 or x = 4
</span>
