Final answer:
The product of 70000 and 444000 is correctly calculated using scientific notation and significant figures, resulting in a final answer of 3.1 × 10ⁱ⁰.
Step-by-step explanation:
To calculate 70000 × 444000, you can either use a calculator or multiply the numbers by hand. If we were to do this calculation step by step without a calculator, it would involve multiplying each digit of one number by each digit of the other and then summing the results according to their positional value. However, for simplicity and to manage more than 100 words, let's use a straightforward approach employing scientific notation and significant figures.
Writing the numbers in scientific notation, we convert 70000 to 7 × 104 and 444000 to 4.44 × 105. Multiplying these two would give us 7 × 4.44 × 104+5 which is 31.08 × 109. To express this with the proper number of significant figures, we look at our original numbers. Both 70000 and 444000 have two significant figures, so our result should also have two significant figures: 3.1 × 1010.
