1. (6.0•10^5) •(3.0•10^4)
To multiply numbers in scientific notation, you need to multiply the coefficients and add the exponents. Let's calculate it step by step:
1. Multiply the coefficients: 6.0 x 3.0 = 18.0
2. Add the exponents: 10^5 x 10^4 = 10^(5+4) = 10^9
So, the result is 18.0 x 10^9.
In scientific notation, we want the coefficient to be between 1 and 10. Since 18.0 is already in that range, we can write our final answer as:
1.8 x 10^10
