Question

What is 500,000,000,000 in scientific notation also 0.00000000005

Answer 1

500,000,000,000 = 5 × 10^11

0.00000000005 = 5 × 10^-11

Answer 2

Answer:

$500,000,000,000=5.0\times 10^{11}$

$0.00000000005=5.0\times10^{-11}$

Step-by-step explanation:

We are asked to write the given numbers in scientific notation.

We know two write a number in scientific notation, we need two factors. One is between 0 and 10 and second is power of 10.

$500,000,000,000=5.0\times 100,000,000,000$

We have 11 zero after 10, so we can write it as $10^{11}$.

$500,000,000,000=5.0\times 10^{11}$

Therefore, our required number would be $5.0\times10^{11}$.

We can see that 0.00000000005, there are 11 digits after decimal, this means that 5 is divided by $10^{11}$.

$0.00000000005=5.0\times \frac{1}{10^{11}}$

Using property $\frac{1}{a^b}=a^{-b}$, we will get:

$0.00000000005=5.0\times10^{-11}$

Therefore, our required number would be $5.0\times10^{-11}$.
