Step-by-step explanation:

For this exercise is important to remember that equivalent expression have the same value.

Then given the following expression provided in the exercise:

(5x)3

You can find equivalent expression by:

-  Changing the position of 3:

3(5x)     (This matches with the first option)

- Solving the multiplication indicated. Then:

(5x)3=15x      (This matches with the fourth option)

- Writting x3 inside the parentheses:

Find the area bounded by the graphs of the indicated equations over the given interval.
NeX [460]

Answer:

48

Step-by-step explanation:

y = 0

is basically the horizontal axis.

First, find the integral of x^2-25.

Remember that

integral of a constant is that constant times x.

Also that

to take the integral of a power function, add 1 to the degree and divide by that same degree.

y =  {x}^{2}  - 25

We then get

\frac{ {x}^{3} }{3}  - 25x

Evaluate at -3

\frac{ - 3 {}^{3} }{3}  - 25( - 3)

- 27 + 75 = 48

Then we evaluate at 0

\frac{0 {}^{3} }{3}  - 25(0) = 0

Next, we subtract the the answer then we get

48 - 0 = 48

Write kkkkknn in exponenential form
horrorfan [7]
I count five 'k's there, so that part of the expression is

                                     k⁵  .

Two 'n's form the rest of it, so that part is  n² .

The parts are multiplied, so the simplest form of the expression is

                                     k⁵ n²  .
