WebUsing logarithms to solve real world problems Interest Compounded Annually Suppose that $10,000 is invested at 6% interest compounded annually. In t years an investment will grow to the amount expressed by the function, where t is time (in years). (See the plot in Figure 1). How long will it take to accumulate $20,000 in the account? Make the base on both sides of the equation the SAME so that if bM=bN\large{b^{\color{blue}M}} = {b^{\color{red}N}}bM=bN then M=N{\color{blue}M} = {\color{red}N}M=N 1. In other words, if you can express the exponential equations to have the same base on both sides, then it is okay to set their … See more 1) Zero Property 2) Negative Exponent Property 3) Product Rule 4) Quotient Rule 5) Power to a Power Rule Let’s take a look at some examples!
