Divide 1.95 x 10^6 and 3.2 x 10^4

1 answer

To divide numbers in scientific notation, you divide the coefficients and subtract the exponents.

So, (1.95 x 10^6) / (3.2 x 10^4) can be calculated as follows:

1.95 / 3.2 = 0.609375 (rounded to 6 decimal places)

10^6 / 10^4 = 10^(6-4) = 10^2 = 100

Therefore, (1.95 x 10^6) / (3.2 x 10^4) = 0.609375 x 100 = 60.9375 x 10 = 6.09375 x 10^1.

Rounded to one significant figure, the answer is approximately 6.1 x 10^1.
