Answer:

6^4(6^-5)

ex: a^(x)

a = base

x=power = index

6^4 .(6^-5)

6^(4+(-5)

6^(4 - 5)

6^(-1)

3) An $1,000 investment is made in a trust fund at an annual percentage rate of 12%,
Elina [12.6K]

We need to find the interest rate in order to solve this problem:

.12/12 = (.01)

The number of years is unknown. T represents time in the following formula:

1000 (initial investment)

2000 (balance after t years from investment)

$1000 (1 + .01)^{12t}=$2000

In order to isolate the exponential term, both sides must be divided by 1000.

(1+.01)^{12t}=2

By using natural logarithm:

Ln(1+.01)^{12t} =Ln2\\(12t)Ln(1+.01)=Ln2\\

By dividing both sides of the equation by (12)Ln(1+.01)

t=\frac{Ln(2)}{(12)Ln(1+.01)} =5.805yrs
