4.5 × 107
4.5 × 109
45 × 106
6.48 × 107
To simplify the expression, we can divide 5.4 by 1.2 and multiply 10^12 by 10^(-3). This gives us:
5.4 / 1.2 = 4.5
10^12 × 10^(-3) = 10^(12 + (-3)) = 10^9
Therefore, the expression can be simplified to 4.5 × 10^9. Hence, the correct answer is "b) 4.5 × 10^9".
