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
