The use national debt was 2.9617x10^13 in 2021 and 3.98x10^11 in 1071 find how much the debt increased in the 50 year period

To calculate the increase in national debt over a 50-year period, we need to subtract the initial debt from the final debt.

Given:
Initial debt in 2021 = 2.9617x10^13
Final debt in 1071 = 3.98x10^11

Step 1: Convert the scientific notation to standard notation.
2.9617x10^13 = 29,617,000,000,000
3.98x10^11 = 398,000,000,000

Step 2: Calculate the debt increase.
Debt increase = Final debt - Initial debt

Debt increase = 398,000,000,000 - 29,617,000,000,000

Step 3: Calculate the magnitude of the debt increase.
Debt increase = -29,218,000,000,000

Therefore, the national debt increased by approximately $29,218,000,000,000 over the 50-year period.

To find the increase in the national debt over a 50-year period, you will need to calculate the difference between the debt in 2021 and the debt in 1071.

First, let's convert the given values into standard decimal notation:

National debt in 2021: 2.9617 x 10^13
National debt in 1071: 3.98 x 10^11

Now, we can calculate the increase in the national debt over the 50-year period:

Increase in national debt = National debt in 2021 - National debt in 1071

In decimal notation:

Increase in national debt = 2.9617 x 10^13 - 3.98 x 10^11

Since the exponents are different, we need to make them the same by adjusting the respective factors:

2.9617 x 10^13 - 0.3980 x 10^13

Next, we subtract the two values:

2.9617 x 10^13 - 0.3980 x 10^13 = 2.5637 x 10^13

Therefore, the national debt increased by approximately 2.5637 x 10^13 over the 50-year period.

To find the increase in the national debt over the 50-year period, we need to subtract the debt in 1071 from the debt in 2021.

Debt increase = Debt in 2021 - Debt in 1071

Debt in 2021 = 2.9617x10^13
Debt in 1071 = 3.98x10^11

Debt increase = 2.9617x10^13 - 3.98x10^11
= 29.617x10^11 - 3.98x10^11 (converting to scientific notation)
= (29.617 - 3.98)x10^11 (subtracting)
= 25.637x10^11

Therefore, the debt increased by 25.637x10^11, or 2.5637x10^12, over the 50-year period.
