1. The problem statement, all variables and given/known data (2.5 x 10^24)(4.5 x 10^-9) / (3 x 10^4) 2. Relevant equations 3. The attempt at a solution I know that when multiplying base ten numbers with exponents you add the exponents (ie: 10^2 x 10^3 = 10^5) ad that when dividing, the exponents are subtracted. I'm not sure what my first step would be towards simplifying this equation.
