Answer: <font color=red>703</font>


Work Shown


Loan payment formula
P = (L*i)/(1 - (1+i)^(-n))
where,
P = annual payment in billions of dollars
L = loan amount in billions of dollars
i = interest rate per year
n = number of years


In this case
L = 5000 (since $5 trillion = $5*1000 = $5000 billion)
i = 0.05
n = 9


Let's determine the annual payment
P = (L*i)/(1 - (1+i)^(-n))
P = (5000*0.05)/(1 - (1+0.05)^(-9))
P = 703.450399878939 approximately
P = <font color=red>703</font> after rounding to the nearest whole number


This represents <font color=red>$703 billion</font> aka $703,000,000,000
There are 9 zeros after the 703.
In scientific notation it would be 7.03 * 10^11
The exponent 11 means "move the decimal point 11 spots to the right" to go from 7.03 to that massive number shown above.
