D) 3.33×10⁻²

Answer 1

To simplify the given expression and express the answer in standard form, multiply the numerator, multiply the denominator, and divide the numerator by the denominator. The answer is 8.33×10⁴.

Step-by-step explanation:

To simplify the expression 0.0012×0.25×10³ ÷(0.036×0.001) and express the answer in standard form, we can follow these steps:

1. Multiply the numbers in the numerator: 0.0012 × 0.25 × 10³ = 0.0003 × 10³ = 0.3 × 10⁰.
2. Multiply the numbers in the denominator: 0.036 × 0.001 = 0.000036.
3. Divide the numerator by the denominator: (0.3 × 10⁰) ÷ 0.000036 = 8.33 × 10⁴.

Therefore, the answer is A) 8.33×10⁴.
