Question

4.66 × 10^−5 − 7.34 × 10^−7

Answer 1

Subtract this Scientific Notation: 4.66 × 10^−5 − 7.34 × 10^−7

Answer 2

The U.S. 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 point)

Answer 3

This isn't accurate!

Answer 4

To subtract these two numbers, we need to ensure that they have the same exponent.

4.66 × 10^−5 = 0.0000466

7.34 × 10^−7 = 0.000000734

Now, we can subtract them:

0.0000466 - 0.000000734 = 0.000045866

Therefore, 4.66 × 10^−5 - 7.34 × 10^−7 = 0.000045866.

Answer 5

To subtract these numbers in scientific notation, we need to have the same exponent.

4.66 × 10^-5 can be written as 0.0000466
7.34 × 10^-7 can be written as 0.000000734

Now, we can subtract these two numbers:
0.0000466 - 0.000000734 = 0.000045866

Therefore, 4.66 × 10^-5 - 7.34 × 10^-7 = 0.000045866.

Answer 6

To find how much the U.S. national debt increased over the 50-year period from 1971 to 2021, we can subtract the debt in 1971 from the debt in 2021.

Debt in 2021: $2.9617×10^13 = $29,617,000,000,000
Debt in 1971: $3.98×10^11 = $398,000,000,000

Amount of increase = Debt in 2021 - Debt in 1971
Amount of increase = $29,617,000,000,000 - $398,000,000,000
Amount of increase = $29,218,000,000,000

Therefore, the U.S. national debt increased by $29,218,000,000,000 (29.218 trillion dollars) over the 50-year period.

Answer 7

I apologize for the error in my previous response. Let's calculate the increase in the U.S. national debt correctly this time.

Debt in 2021: $2.9617×10^13 = $29,617,000,000,000
Debt in 1971: $3.98×10^11 = $398,000,000,000

To find the increase, we need to 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 U.S. national debt increased by $29,219,000,000,000 (29.219 trillion dollars) over the 50-year period. Thank you for pointing out the error, and I appreciate your understanding.
