Question

A social media website currently has 1000 members. The number of people that join the website triples every month. After how many months will the website have more than 1 million members? Talk the beginning as month 0

Answer 1

At 7 months it would b3 2,187,000 hope this helps

Answer 2

Members = 1,000*3^t where t = months
So after
0 months  1,000 members
1 month    3,000 members
2 months  9,000 members

If we are to solve that for a million:
Members/1,000 = 3^t
1,000,000/1,000 = 3^t
1,000 = 3^t 
Taking logs of both sides
log 1,000 = time*log(3)
3 = time * 0.4771212547
time = 3/ 0.4771212547
time = 6.2877098229 months
Okay about 6.29 months
