Answer:
153/20
Step-by-step explanation:
I assume you're asking

So

=

So first factor it
1008=2*2*2*2*3*3*7
group them in similar pairs
1008=(2*2)(2*2)(3*3)*7
now remember we can do

so

=
2*2*3*

=
12√7
the answer is B
Answer:1 2 and 4
Step-by-step explanation:
I just did it
Choice A is false because they are rounding to the nearest tenth (one decimal place) and not nearest hundredth (two decimal places)
Choice B is false as well because 3.825 should round to 3.83. The 5 at the end tells you to round up.
Choice C is false too. The value 3.824 should round to 3.82. Not sure how they got 3.81, so it seems like a deliberate trick question or silly answer.
Choice D is true. The three decimal values are rounded properly to the correct number of decimal places.
Therefore choice D is the answer
I think the answer is 3 but I’m not sure.
Hope this helps!
