The u.s national debate was 2.9617*10¹³ in 2021 and 3.98*10¹¹ in 1971 find how much the debt increased in the 50 yr period
To determine how much the debt increased over the 50-year period, we need to find the difference between the debt in 2021 and the debt in 1971.
Debt in 2021: 2.9617 * 10^13
Debt in 1971: 3.98 * 10^11
Debt increased = Debt in 2021 - Debt in 1971
= (2.9617 * 10^13) - (3.98 * 10^11)
To subtract these values, we need to have them in the same exponent format. Let's convert both of them to scientific notation with the same exponent:
Debt in 2021 = 29.617 * 10^12
Debt in 1971 = 0.398 * 10^13
Now we can subtract them:
Debt increased = (29.617 * 10^12) - (0.398 * 10^13)
= 29.617 * 10^12 - 0.398 * 10^13
To subtract these values, we keep the same exponent since they are already in scientific notation and subtract the coefficients:
Debt increased = 29.617 - 0.398 = 29.219
Therefore, the debt increased by approximately 29.219 * 10^12 or $29.219 trillion over the 50-year period.
To find how much the debt increased over the 50-year period, you need to calculate the difference between the debt in 2021 and the debt in 1971.
First, let's find the debt increase from 1971 to 2021:
Debt in 2021: 2.9617 * 10^13
Debt in 1971: 3.98 * 10^11
To calculate the debt increase, subtract the debt in 1971 from the debt in 2021:
Debt increase = Debt in 2021 - Debt in 1971
= (2.9617 * 10^13) - (3.98 * 10^11)
To subtract these numbers, you'll need to align the numbers so that their exponents are the same. In this case, we can write 3.98 * 10^11 as 0.00398 * 10^13.
Debt increase = (2.9617 * 10^13) - (0.00398 * 10^13)
Now, since the exponents are the same, you can subtract the coefficients:
Debt increase = 2.9617 - 0.00398
= 2.95772
Finally, multiply the result by 10^13 to get the debt increase in standard notation:
Debt increase = 2.95772 * 10^13
Therefore, the debt increased by approximately 2.95772 × 10^13 in the 50-year period from 1971 to 2021.
To find out how much the debt increased in the 50-year period from 1971 to 2021, we need to calculate the difference between the national debt in 2021 and 1971.
National debt in 2021: 2.9617 * 10¹³
National debt in 1971: 3.98 * 10¹¹
To calculate the increase, we subtract the debt in 1971 from the debt in 2021:
Increase = 2.9617 * 10¹³ - 3.98 * 10¹¹
To subtract these numbers, we need to make sure the exponents are the same. We can do this by converting both numbers to scientific notation with the same exponent:
2.9617 * 10¹³ = 2.9617 * 10¹¹ * 10²
3.98 * 10¹¹ = 3.98 * 10¹¹ * 10⁰
Now we can subtract the numbers:
Increase = (2.9617 * 10¹¹ * 10²) - (3.98 * 10¹¹ * 10⁰)
When multiplying numbers in scientific notation, we add the exponents and multiply the coefficients:
Increase = (2.9617 * 10¹¹) * (10²) - (3.98 * 10¹¹) * (10⁰)
Increase = (2.9617 * 10¹¹) * (10² - 0) - (3.98 * 10¹¹)
Increase = (2.9617 * 10¹¹) * (10²) - (3.98 * 10¹¹)
Increase = 2.9617 * 10¹³ - 3.98 * 10¹¹
Therefore, the debt increased by approximately 2.9617 * 10¹³ - 3.98 * 10¹¹ in the 50-year period.
