Answer:
4.4 x 10^4
Step-by-step explanation:
(1.892 x 10^8)/(4.3 x 10^3) can be written as:
(1.892/4.3)*(10^8/10^3)
Do each calculation separately:
---------
(1.892/4.3) = 0.44
----------
(10^8/10^3) = 10^5 [The coefficient 3 in the denominator is subtracted from the coefficient in the numerator]
Now put the two together: 0.44 x 10^5
Move the decimal point so that it is to the right of the first digit: 4.4 and then decrease the 10^5 to 10^4.
Answer: 4.4 x 10^4
