    Answer: 3 × 10⁴ miles²

    Step-by-step explanation:

    Given that:

    Estimated Surface area of Lake = 30,000 square miles

    Expressing the estimated area as a whole number multiplied by a power of ten

    Hence, we are required to express the surface area in standard form:

    30,000 miles ² in standard format:

    30,000 is equivalent to (3 × 10,000)

    3 is a whole number

    10,000 = (10 * 10 * 10 * 10)= 4 th power of 10

    10,000 = (10 * 10 * 10 * 10) = 10⁴

    Hence,

    3 × (10 * 10 * 10 * 10) = 3 × 10⁴ miles²
