Final answer:
The product of 3.5 x 10^6 and 5 x 10^-4 is 1.75 x 10^3.
Step-by-step explanation:
To find the product of 3.5 x 10^6 and 5 x 10^-4, we multiply the numbers and add the exponents.
The product of the numbers is 3.5 x 5 = 17.5.
The sum of the exponents is 6 + (-4) = 2.
Therefore, the final product is 17.5 x 10^2.
In scientific notation, this can be written as 1.75 x 10^3.
