The quantity 5.85 x 10^4m is equivalent to.....
a.5850 000m
b.5840m
c.58500m
d.0.000585m

To find the equivalent value of 5.85 x 10^4m, we need to understand scientific notation. In scientific notation, a number is expressed as a product of a coefficient (between 1 and 10) and a power of 10.

In this case, the coefficient is 5.85, and the power of 10 is 4. The power of 10 indicates the number of decimal places to move to the right or left.

To convert the scientific notation to standard form (decimal form), we multiply the coefficient by 10 raised to the power of 4:

5.85 x 10^4m = 5.85 * 10,000m = 58,500m

Therefore, the equivalent value of 5.85 x 10^4m is 58,500m, so the answer is option c.
