we have the number

$6-\sqrt[]{-40}$

Remember that

i^2=-1

substitute

$6-\sqrt[]{(i^2)40}$ $6-2i\sqrt[]{10}$

therefore

the real part is 6

the imaginary part is -2√10

Answer:

"4" represents that there are 4 rabbit in the beginning.

Step-by-step explanation:

Given that the population of a species of rabbit triples every year. This

can be modeled by function $f\left(x\right)=4\left(3\right)^x$ and $f(5) = 972$ .

Now we need to find about what does the 4 represent in the given function.

We know that exponential function is given by $f\left(x\right)=a\left(b\right)^x$ . Where "a" represents the initial amount.

we have a=4 in given function $f\left(x\right)=4\left(3\right)^x$ .

So that means "4" represents that there are 4 rabbit in the beginning.
