X Katelyn incorrectly simplified an expression using the steps shown below.
(3 x 10^) (9 x 10) + 0.0002
(27 x 10-2) + 0.0002
= (27 x 10-2) + (2 x 10-4)
= (0.27 x 10 4) + (2 x 10-4)
= 2.27 x 10-8
Which of the following equations from Katelyn's steps are false?
Select all that apply.
Х
(3 x 104) (9 x 10²) + 0.0002 = (27 x 10-2) + 0.0002
(27 x 10-2) + 0.0002 = (27 x 10-2) + (2 x 10-4)
(27 x 10-2) + (2 x 10-4) = (0.27 x 10-4) + (2 x 10-4)
(0.27 x 10-4) + (2 x 10-) = 2.27 x 10-8

answer: group b.

step-by-step explanation:

aloha~! my name is zalgo and i am here to you out on this amazing day. to answer your question, yes, nonzero numbers can have a greatest common factor and that would be 1. still don't get it? let me considering every number is divisible by 1 and hence every number has 1 as a factor of theirs. so, if 2 nonzero numbers didn't share any gcf (greatest common factor), they would still have a factor in common and that would be 1.

i hope that this ! : p
