So, I have to turn the quotient answer into scientific notation.. (answer has to be in scientific notation)

6x10^24/ 8x10^8
- 7.5 x 10^2
- 7.5 x 10^15
- 0.75 x 10^3 *This is the one I pick*
- 0.75 x 10^16

7.5 x 10^2

With scientific notation you have to have a number (less than 10 and higher than zero) multiplied by 10^...

6x10^24 / 8x10^8

= 7.5x10^15

explanation
(6/8) = .75
10^24 / 10^8 = 10^16

so .75 x 10^16
= 7.5 x 10^15

Just to be clear, the number has to be at least 1.0 and less than 10.

In interval notation that would be a number in [1.0,10.0)

To turn the quotient answer into scientific notation, you need to follow these steps:

1. Divide the numbers:
6x10^24 / 8x10^8 = (6/8) x (10^24 / 10^8).

2. Simplify the fraction:
6/8 = 3/4.

3. Divide the powers of 10:
10^24 / 10^8 = 10^(24-8) = 10^16.

4. Put it all together:
(3/4) x 10^16.

Now, to write this in scientific notation, we need to express the fractional part as a decimal between 1 and 10.

5. Convert the fraction to decimal:
3/4 = 0.75.

6. The final answer in scientific notation is:
0.75 x 10^16.

So, the correct option is 0.75 x 10^16.
