divide 1.925 x 10^6 by 2.75

To divide 1.925 x 10^6 by 2.75, we can write it as:

(1.925 x 10^6) / 2.75

To simplify the division, we divide 1.925 by 2.75 and subtract the exponents:

1.925 / 2.75 = 0.7

10^6 / 10^0 = 10^(6-0) = 10^6

Therefore, (1.925 x 10^6) / 2.75 = 0.7 x 10^6 or 7 x 10^5.

which one is correct

Apologies for the confusion. The correct calculation is:

(1.925 x 10^6) / 2.75 = 7 x 10^5

divide 3.5 x 10^2 by 10.5

To divide 3.5 x 10^2 by 10.5, we can write it as:

(3.5 x 10^2) / 10.5

To simplify the division, we divide 3.5 by 10.5 and subtract the exponents:

3.5 / 10.5 = 0.33333...

10^2 / 10^0 = 10^(2-0) = 10^2

Therefore, (3.5 x 10^2) / 10.5 = 0.33333... x 10^2.
