Perform the following calculations without rewriting the numbers in decimal form.
(1.42 × 10^15)(2.4 × 10^13)

After multiplication number will be

Step-by-step explanation:

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    there power will be added and after multiplication number will be

i = 2 / - 5

step-by-step explanation:

evaluation of ( 2 - 4 ) ( p + q ) when p = 2 and q = 5 i, by putting values of p and q,
