If \(1.125 \times 10^k = 0.001125\), the value of k is:
Answer: B
To get from 1.125 to 0.001125, we need to move the decimal point 3 places to the left.
Moving the decimal point to the left corresponds to dividing by powers of 10, or multiplying by 10 to a negative power.
Moving 3 places to the left is equivalent to multiplying by \(10^{-3}\).
Therefore, k = -3.
