Question

Which of the following represents 7.1×10-55 in standard notation?

7100.00
710000
7.1
.000071

Answer 1

0.000071

Step-by-step explanation:

The given number that is given in scientific notation is,
`N=7.1* 10^(-5)`............(1)

We need to write this number in standard notation. A number can be written in scientific notation as :

`N=a* 10^b`..........(2)

In standard notation,
`N=7.1* 10^(-5)=(71)/(10)* 10^(-5)`

`N=(71)/(10^(6))=0.000071`

So,
`7.1* 10^(-5)` is equivalent to
`0.000071`. Hence, the correct option is (d)
