Correct Answer: 3.5
Explanation
where Log2 8√2 → Log2 √128 → Log2 128 1/2 = 1/2 * (Log2 128) → 1/2* (Log2 27) = 7 * 1/2 * (Log2 2) where (Log22) = 1 → 7 * 1/2* 1 = 7/2 or 3.5
where Log2 8√2 → Log2 √128 → Log2 128 1/2 = 1/2 * (Log2 128) → 1/2* (Log2 27) = 7 * 1/2 * (Log2 2) where (Log22) = 1 → 7 * 1/2* 1 = 7/2 or 3.5THIS WEEK's
