The diameter of the solar system is about 300,000,000,000,000 kilometers, which can be written as 3 x 100 kilometers. What is n?

D. 14.

Step-by-step explanation:

As we know, 10 to the second power is 100, to the third power is 1000, and so on. These powers add a zero to the number. Since PEMDAS tells us to do exponents before multiplication, we need to find what power of 10 gives us 100,000,000,000,000. Let's count all the zeros. There are 14 zeroes. This means our answer is D. 14. Let's check, though. 10 to the 14th power is 100,000,000,000,000, and that times 3 is 300,000,000,000,000. That means our answer is correct, it is in fact, D. I hope this helps!

Edit: I changed the answer from 13 to 14 because I realized that 13 is incorrect.

Solve quadratic equation by factoring or using quadratic formula with our free quadratic equation calculator. ... Step 2 : Choose a command relating to the function f(x) you entered above. ... Example 5 Solve x2 + 6x - 7 = 0 by completing the square. ... Now we find half of 6 = 3 and 32 = 9, to give us the number for the blank.
