I will give 97 points and the brainliest to the right answer..

Solving the first expression, we have:

(4.5⋅10^4)⋅(6.6⋅10^−8)

=30.6⋅10^−4

=3.06⋅10^−3

So the first expression goes into the second box.

For the second one, we have:

(2.8⋅10^2)⋅(6.5⋅10^−7)

=18.2⋅10^−5

=1.82⋅10^−4

So the second expression goes into the first box.

Put the third expression into the fourth box and the fourth expression into the third box

which expression represents the approximate length of bc?
