The US national debt was 2.9617 * 10 ^13 and 2021 and free 98 * 10 ^11 and 1971. Find out how much debt increase in the 50 year peirod.
To calculate the increase in the US national debt over the 50-year period from 1971 to 2021, we subtract the debt in 1971 from the debt in 2021.
Debt in 2021: 2.9617 * 10^13
Debt in 1971: 98 * 10^11
Debt increase = Debt in 2021 - Debt in 1971
Debt increase = (2.9617 * 10^13) - (98 * 10^11)
Let's simplify the calculation:
Debt increase = 29.617 * 10^11 - 0.98 * 10^12
Debt increase = 29.617 * 10^11 - 9.8 * 10^11
Debt increase = (29.617 - 9.8) * 10^11
Debt increase = 19.817 * 10^11
Therefore, the increase in the US national debt over the 50-year period from 1971 to 2021 is 19.817 * 10^11.
To find out the increase in the US national debt over a 50-year period, we need to subtract the debt in 1971 from the debt in 2021.
Debt in 1971: 98 * 10^11
Debt in 2021: 2.9617 * 10^13
Debt increase = Debt in 2021 - Debt in 1971
Debt increase = (2.9617 * 10^13) - (98 * 10^11)
To subtract the two numbers, we need to have the same power of 10. Let's convert 98 * 10^11 to 10^13.
98 * 10^11 = (98 * 10^11) * (10^2/10^2)
= (98 * 10^11 * 10^2) / 10^2
= 9.8 * 10^13
Now we can subtract:
Debt increase = (2.9617 * 10^13) - (9.8 * 10^13)
= -6.8383 * 10^13
Therefore, the US national debt increased by approximately -6.8383 * 10^13 (or -68.383 trillion) dollars over the 50-year period. Note that the negative sign indicates a decrease in the debt.
To find out the increase in the US national debt over a 50-year period, you need to subtract the debt value in 1971 from the debt value in 2021. Let's break it down step by step.
First, let's express the debt values in standard numerical form to make calculations easier.
The US national debt in 1971 was:
98 * 10^11 = 98,000,000,000,000
The US national debt in 2021 was:
2.9617 * 10^13 = 29,617,000,000,000
Next, subtract the debt in 1971 from the debt in 2021:
29,617,000,000,000 - 98,000,000,000,000 = - 68,383,000,000,000
The result is negative because the debt in 1971 was higher than the debt in 2021.
So, the US national debt decreased by approximately 68.383 trillion dollars over the 50-year period.
