In 2005, the us mint in denver produced 4.04 x 10^8 oregon state quarters. the us mint in philadelphia produced 7.12 x 10^7 oregon state quarters. considering the other two us mint locations did not produce any quarters, how many oregon state quarters were minted in 2005? express your answer in scientific notation. and you

The answer to this item is determined by adding the number of Oregon State quarters minted in both Philadelphia and Denver. To be able to do so, we expressed one of the scientific notation the same as the other. We may expressed 4.04 x 10^8 as 40.4 x 10^7. Adding up the values,

    n = (40.4 x 10^7) + (7.12 x 10^7)
    n = 47.52 x 10^7

Similarly, this can also be expressed as 4.752 x 10^8

4.752 x 10^8
