Solve the equation log8x – 4log8x = 2

A. 1/4

B. 1/2

C. 1

D. 2

E. 4

Correct Answer: Option A

**A. 1/4**

Explanation

log8x – 4log8x = 2; log8x – log8x4 = 2

log8x/x4 = 2

x/x4 = 82 = 1/x3 = 64

x3 = (1/4)3; x = 1/4

Solve the equation log8x – 4log8x = 2

A. 1/4

B. 1/2

C. 1

D. 2

E. 4

Correct Answer: Option A

**A. 1/4**

Explanation

log8x – 4log8x = 2; log8x – log8x4 = 2

log8x/x4 = 2

x/x4 = 82 = 1/x3 = 64

x3 = (1/4)3; x = 1/4
