Note: when solving for K, round to the four decimal place.

A country's population in 1995 was 184 million. in 2002 it was 188 million. estimate the population in 2006 using exponential growth formula. round your answer to the nearest millions?

184^n =188

introducing log

log (base184) 188=log 188/log184 =n

n= 1.004124

growth = X^ 1.004124

IF 1995 =n=0 and x being value of population in 1995

equation will be

184million^(1.004124(n))

in 2006 population will be

n= 11

population will be

=184^(1.004124*11)

= 3.6*10^25 million

sorry let me update it. It is wrong.

184^(x^n)= 188

if 1995 n=0

in 2002 n =7

184000000^(x^7)=188000000

introducing log

log (base184000000) 188000000=log 188000000/log184000000 =x^7 = 1.00113

x^7 =1.00113

x =7th root of 1.00113

x=1.0001614

formula is thus

184000000^(1.0001614^n)

in 2006 population will be

n=2006-1995=11

184000000^(1.0001614^11)= 184000000^1.001776 =190,326712.2 = 190 million
