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

could you reply to this with the question so i can ?

fist on the left goes with the third on the right. second on the left goes with the fourth on the right. third on the left goes with the second on the right. the fourth on the left goes with first on the right
