The US national debt was \$ 2.9617 * 10 ^ 13 * in * 2021 and \$ 3.98 * 10 ^ 11 * in * 1971 Find how much the debt increased in the 50-year period (1 p
To calculate the increase in the national debt over the 50-year period, we subtract the debt in 1971 from the debt in 2021.
Debt increase = Debt in 2021 - Debt in 1971
Debt increase = \$2.9617 * 10^13 - \$3.98 * 10^11
To subtract these numbers, we need to express them in the same scientific notation. We can do this by dividing the larger number by 10 until their exponents are the same. In this case, we divide \$2.9617 * 10^13 by 10^2 to get the same exponent as \$3.98 * 10^11.
Debt increase = (\$2.9617 * 10^13 / 10^2) - \$3.98 * 10^11
Debt increase = \$2.9617 * 10^11 - \$3.98 * 10^11
Now we can subtract the numbers and keep the result in scientific notation:
Debt increase = \$2.9617 * 10^11 - \$3.98 * 10^11
Debt increase = -\$1.0183 * 10^11
Therefore, the national debt increased by approximately -\$1.0183 * 10^11 (negative because it is a decrease) in the 50-year period.
To find the increase in the US national debt over the 50-year period from 1971 to 2021, we will subtract the debt in 1971 from the debt in 2021.
Debt in 2021: \$2.9617 * 10^13
Debt in 1971: \$3.98 * 10^11
To subtract these two numbers, we need to make sure their powers of 10 are the same. We can do this by converting both numbers to scientific notation with the same exponent.
Debt in 2021: \$29.617 * 10^12
Debt in 1971: \$0.398 * 10^12
Now we can subtract the two debt amounts:
Debt increase = Debt in 2021 - Debt in 1971
Debt increase = (\$29.617 * 10^12) - (\$0.398 * 10^12)
Debt increase = \$29.219 * 10^12
Therefore, the US national debt increased by \$29.219 * 10^12 (or \$29.219 trillion) during the 50-year period from 1971 to 2021.
To find how much the US national debt increased over a 50-year period, we can subtract the debt in 1971 from the debt in 2021.
First, let's convert the scientific notation to regular decimal notation:
Debt in 2021: \$29,617,000,000,000
Debt in 1971: \$398,000,000,000
Now, we can subtract the debt in 1971 from the debt in 2021:
\$29,617,000,000,000 - \$398,000,000,000 = \$29,219,000,000,000
Therefore, the US national debt increased by \$29,219,000,000,000 over the 50-year period.
