Q
Q: What is the value of log2(8) + log2(4)?
Solution:
log2(8) = 3 and log2(4) = 2, so 3 + 2 = 5.
Steps: 6
Show Steps
Step 1: Understand that log2(8) means 'to what power do we raise 2 to get 8?'.
Step 2: Since 2 raised to the power of 3 equals 8, we find that log2(8) = 3.
Step 3: Next, understand that log2(4) means 'to what power do we raise 2 to get 4?'.
Step 4: Since 2 raised to the power of 2 equals 4, we find that log2(4) = 2.
Step 5: Now, add the two results together: 3 (from log2(8)) + 2 (from log2(4)).
Step 6: The final result is 5.
