"Exponential growth" is not one equation but a concept. Example: If I put $1,000 in the Bank and the Bank pay 5% interest compounded annually, then my money will grow exponentially, depending on the interest rate and the number of years. So, at 5% for 10 years, my money will grow: $1,000 X 1.05^10=$1,628.89. But, if I left my money in the Bank for 30 years, then: $1,000 X 1.05^30=$4,321.94. Also, a higher interest rate will have the same effect. So, a 10% interest rate will give:$4,321.94 for 10 years, and: $17,449.40 for 30 years.....and so on.
