Question

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

Answer 1

Answer:

After multiplication number will be $3.5\times 10^{-5}$

Step-by-step explanation:

We have given numbers which has to multiply using scientific notation

$7\times 10^{-9}\times 5\times 10^5$

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 $7\times 10^{-9}\times 5\times 10^5$ there power will be added and after multiplication number will be $35\times 10^{-4}=3.5\times 10^{-5}$
