Use scientific notation to divide the following 2 numbers .Express the answer using scientific notation; retain at least3 decimal places
(9.4*10^6)/(4.97*10^2)
(9.4/4.97) * 10^4
To divide numbers expressed in scientific notation, we can follow these steps:
Step 1: Divide the decimal parts of the numbers.
9.4 / 4.97 ≈ 1.888533
Step 2: Divide the powers of 10 by subtracting the exponent of the divisor from the exponent of the dividend.
10^6 / 10^2 = 10^(6-2) = 10^4
Step 3: Express the answer in scientific notation by combining the result from Step 1 with the result from Step 2.
1.888533 * 10^4
However, we need to retain at least 3 decimal places, so we can round the result to the nearest thousandth:
1.889 * 10^4
Therefore, the answer, expressed in scientific notation and retaining at least 3 decimal places, is approximately 1.889 * 10^4.
