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

`500,000,000,000=5.0* 10^(11)`

`0.00000000005=5.0*10^(-11)`

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* 100,000,000,000`

We have 11 zero after 10, so we can write it as
`10^(11)`.

`500,000,000,000=5.0* 10^(11)`

Therefore, our required number would be
`5.0*10^(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* (1)/(10^(11))`

Using property
`(1)/(a^b)=a^(-b)`, we will get:

`0.00000000005=5.0*10^(-11)`

Therefore, our required number would be
`5.0*10^(-11)`.
