Questions & Step-by-Step Solutions

What is the value of log_10(1000) + log_10(0.01)?
Correct Answer: 1
  • Step 1: Understand that log_10(x) means 'to what power must 10 be raised to get x'.
  • Step 2: Calculate log_10(1000). Since 10^3 = 1000, we find that log_10(1000) = 3.
  • Step 3: Calculate log_10(0.01). Since 10^-2 = 0.01, we find that log_10(0.01) = -2.
  • Step 4: Add the two results together: 3 (from log_10(1000)) + (-2) (from log_10(0.01)).
  • Step 5: Simplify the addition: 3 - 2 = 1.
