Step-by-step explanation:

F=5.77X10^9(1.032^(y-1985)), we want to know when this is:
2.2X10^12=5.77X10^9(1.032^(y-1985))
381.2825=1.032^(y-1985)
ln(3,812825)=(y-1985)ln(1.032)
ln(3.812825)/ln(1.032)=y-1985
y=1985+ln(3.812825)/ln(1.032)
y≈2027.5
So GDP will reach 2.2 trillion during the year 2027.
You use division
over 2 or 4 or 3 or 5 or 7 and so on
in this case 2 is good
64 = 2 * 2 * 2 * 2 * 2 * 2 ( use division) = 2^6
16 = 2 * 2 * 2 * 2 = 2^4
number reminder
64 0
32 0
16 0
8 0
4 0
2 0
1 1
so 64 = 2^6 (number of zeros) no reminder
I would say 6 . \/ /\ | __ ⇘ ⇙ ( Those are the directions I was going for)
I hope this helped !
