Simplify. Write in scientific notation. 0.5(8 × 10^5)
You know what, try this yourself. So start with 10^5 = 10,000 and then multiply by 8 and .5, then convert that to scientific notation.
I got 400,000 when multiplying
ohhhhhhh! is it 4 x 10 ^ 5 ?????????????????????????
No, it should be 40,000... And yes, it's 4*10^5 is the same thing.
