1.6 x 10^8)(5.8 x 10^6)

zubka84 [21]

2.32x10^8. I'm in Honors Chemistry in high school, I just inputted this into a calculator which is easy. Otherwise you can just take them out of scientific notation and into standard form which is this:
(160000000)(5800000)/4000000=232000000. And then convert it back.

Find all cube roots of -1000i

NemiM [27]

Answer:

10i

Step-by-step explanation:

Since i^2 = -1, and 1000 = 10^3, we can instinctively guess that the answer is 10i. We can validate this by cubing it, yielding 1000i^3, or -1000i.
