Answer 3

The expression 4.66x10^-5 - 7.34x10^-7 can be simplified as follows:

4.66x10^-5 - 7.34x10^-7
= 4.66*10^-5 - 7.34*10^-7

To subtract these two numbers, we need to have the same exponent, so we convert them to the same power of 10.

= 4.66*10^-5 - 0.734*10^-6 (converting 7.34 to exponent -6)

Now that both numbers have the same exponent, we can subtract them.

= (4.66 - 0.734) * 10^-5

Simplifying further,

= 3.926 * 10^-5

Therefore, 4.66x10^-5 - 7.34x10^-7 is equal to 3.926x10^-5.

Answer 4

My apologies for the previous incorrect response.

To subtract 7.34 × 10^-7 from 4.66 × 10^-5, we need to have the same exponent:

4.66 × 10^-5 - 7.34 × 10^-7 = 4.66 × 10^-5 - 0.00734 × 10^-5

Now we can subtract them:

4.66 × 10^-5 - 0.00734 × 10^-5 = (4.66 - 0.00734) × 10^-5

Simplifying further:

4.65266 × 10^-5

Therefore, 4.66 × 10^-5 - 7.34 × 10^-7 equals 4.65266 × 10^-5.

Answer 5

To find the increase in the national debt over the 50-year period, we need to subtract the debt in 1971 from the debt in 2021.

$2.9617 × 10^13 - $3.98 × 10^11

To subtract these numbers, we need to have the same exponent, so we convert the second number to the same power of 10.

$2.9617 × 10^13 - $0.398 × 10^13 (converting $3.98 × 10^11 to exponent 13)

Now that both numbers have the same exponent, we can subtract them.

($2.9617 - $0.398) × 10^13

Simplifying further:

$2.5637 × 10^13

Therefore, the increase in the debt over the 50-year period is $2.5637 × 10^13 or $25.637 trillion.
