Answer:
The answer to your question is letter D. x = 64
Step-by-step explanation:
Equation
log x 8 = 0.5
Express the log as a exponential equation
x[tex]x^{0.5}[/tex] = 8
Express the power as a fraction
[tex]x^{1/2} = 8[/tex]
[tex]\sqrt{x^{2}}[/tex]
Look for a number which squared root is 8
[tex]\sqrt{64} = 8[/tex]
Then
x = 64
