Final answer:
To find out how much farther 4 x 10^16 is from 8 x 10^16, subtract the coefficients of the powers of ten, which shows that the difference between the two numbers is 4 x 10^16 units.
Step-by-step explanation:
To find out how much farther 4 x 1016 is from 8 x 1016, we need to subtract the smaller number from the larger number. This is a simple subtraction problem involving scientific notation, where we keep the same power of ten and subtract the coefficients.
The difference is:
Write both numbers with the same power of ten: 4 x 1016 and 8 x 1016.
Subtract the coefficients (8 - 4) while maintaining the power of ten.
The result is (8 - 4) x 1016, which simplifies to 4 x 1016.
Therefore, 4 x 1016 is 4 x 1016 units farther from 8 x 1016.
