Question

Arithmetic Operations with Numbers Written Using Scientific Notation
(7 × 10^−9)(5 × 10^5)

Answer 1

After multiplication number will be
`3.5* 10^(-5)`

Explanation:

We have given numbers which has to multiply using scientific notation

`7* 10^(-9)* 5* 10^5`

We have to multiply the above number using scientific notation

We know that when two number are multiplied then there exponent power is being added

So when we multiply
`7* 10^(-9)* 5* 10^5` there power will be added and after multiplication number will be
`35* 10^(-4)=3.5* 10^(-5)`
