Thank u very much and if u could help eith the first one (the writing one) it would help alot
I judt don't know if I do it correctly I get the right awnswrs but it says to "describe how to divide numbers in scientific notation" all I do is take them out of scientific notation then divide

0.000027 and 0.000009 correct?
otherwise i cant help....
Yep
Ok well here 0.000027 ÷ 0.000009
= 2.7 x 10^-5 ÷ 9.0 x 10^-6
= (2.7/9) x 10^(-5 - (-6))
= .3 x 10^1
= 3
= 2.7 x 10^-5 ÷ 9.0 x 10^-6
= (2.7/9) x 10^(-5 - (-6))
= .3 x 10^1
= 3
mke sure to rewrite it
Thank u
