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

Answer 1

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.
