Multiply (3.1 x 10 squared) (2.0 x 10 cubed)

OpenStudy (anonymous):

So, $(3.1 \times10^2)(2\times10^3)?$

OpenStudy (anonymous):

I believe it is: $(31^2)(20^3) = 620^5$

OpenStudy (anonymous):

or, 6.2 times 10 to the 5.

OpenStudy (anonymous):

620000

OpenStudy (anonymous):

yes. but if you need to keep in scientific notation then it is 6.2 X 10^5

OpenStudy (anonymous):

Britt, you don't get the same answer with 6.2x 10^5 and 620^5. I did mine according to pemdas and kept the exponents there as a simplification.

OpenStudy (anonymous):

Alvin and Brittany are right, i was wrong haha

OpenStudy (anonymous):

distributive property

OpenStudy (anonymous):

no. it's just how you add items in scientific notation... ha

OpenStudy (anonymous):

you multiple the terms being multiplied in the scientific notation and then add the exponents that are with the 10's

OpenStudy (anonymous):

humm.. that sounded weird
