Question

what is the solution to (3*10^2)*(5*10^5) written in scientific notation

Answer 1

What do you get when you evaluate that?

Answer 2

3x10^2 =300 and
5x10^5 = 500000

So what is 300 x 500000?

Answer 3

It is 150000000, so now we can convert this to scientific notation (which is just a more simplified way of writing that large number).

Answer 4

To do this we can move the decimal to the right 8 times. So in scientific notation 150000000 would become 1.5x10^8

Answer 5

Hope that makes sense now :)

Answer 6

the answer is correct however,
the purpose of scientific notation is to work with large/small numbers without all those zeros
also learn how to regroup and work with exponents
