A Top NBA player can earn about 2.5 x 10 7th power dollars each year. If john earns $40,000 per year at his starting job out of college, how many times greater is the NBA player's salary?

25 millions / 40 k = 625

Answer: Hello mate!

let's solve this in the given notation:

The yearly salary of an NBA player is $2.5x10^7

The yearly salary of John is $40000, this has 4 zeros, so we can write this as $4x10^4

Then the relation between the salary can be calculated as:

(2.5x10^7) / (4x10^4)

using the distributive property, we can solve it as:

(2.5/4) * (10^7/10^4) = 0.625x10^ (7 - 4) = 0.625x10^3

we can rewrite this as:

6.25x10^2, or 625

Then the yearly salary of the NBA player is 625 times bigger than the one of John.
