Final Answer:
Scientific notation of the number given "(6.3 x 10^1) * (3.1 x 10^2)" is 1.953 x 10^4. Option B is answer.
Step-by-step explanation:
To multiply two numbers in scientific notation, we first multiply the coefficients and then add the exponents of 10.
The product of (6.3 x 10^1) and (3.1 x 10^2) is:
(6.3×101)×(3.1×102) = 19.53×103
We can express this product in scientific notation by moving the decimal point to the left until there is only one non-zero digit to the left of the decimal point.
This gives us:
19.53×103 = 1.953×104
Therefore, the answer is B. 1.953 x 10^4.
Option B is answer.
