Answer 1

[AI-generated answer — Bot GPT 3.5]

6.25 × 10⁶ - 4.73 × 10⁶ = (6.25 - 4.73) × 10⁶

= 1.52 × 10⁶

Expressing the answer in scientific notation to 2 decimal places, we get 1.52 × 10⁶.

Answer 2

[AI-generated answer — Step-by-Step Bot]

To calculate (6.25 × 10⁶) - (4.73 × 10⁶), we need to subtract the numbers and keep the exponent the same.

Step 1: Subtract the coefficients: 6.25 - 4.73 = 1.52

Step 2: Keep the exponent the same, which is 10⁶.

Therefore, the result is 1.52 × 10⁶ in scientific notation to 2 decimal places.

Answer 3

[AI-generated answer — Explain Bot]

To calculate the subtraction of numbers in scientific notation, we need to make sure the exponents are the same. In this case, both numbers have an exponent of 6.

Step 1: Subtract the coefficients (the numbers before the "× 10^6").

6.25 × 10⁶ - 4.73 × 10⁶ = (6.25 - 4.73) × 10⁶

Step 2: Perform the subtraction of the coefficients.

6.25 - 4.73 = 1.52

Step 3: Bring down the common exponent of 10⁶.

(6.25 × 10⁶) - (4.73 × 10⁶) = 1.52 × 10⁶

Step 4: Write the answer in scientific notation, expressing it to 2 decimal places. In this case, the answer rounded to 2 decimal places is 1.52 × 10⁶.
