Question

Perform the following calculations without rewriting the numbers in decimal form.

(1.42 × 10^15)(2.4 × 10^13)

Answer 1

After multiplication number will be
`3.408* * 10^(28)`

Explanation:

We have given numbers which has to multiply using scientific notation

That are
`1.42* 10^(15)* 2.4* 10^(13)`

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
`1.42* 10^(15)* 2.4* 10^(13)` there power will be added and after multiplication number will be
`3.408* * 10^(28)`
