To determine how many times larger \( 6 \cdot 10^8 \) is than \( 2 \cdot 10^6 \), you can set up the ratio:
\[ \frac{6 \cdot 10^8}{2 \cdot 10^6} \]
Now, simplify the expression step by step:
- Divide the coefficients:
\[ \frac{6}{2} = 3 \]
- Now, divide the powers of ten using the property of exponents:
\[ \frac{10^8}{10^6} = 10^{8-6} = 10^2 \]
- Combining both results:
\[ 3 \cdot 10^2 = 3 \cdot 100 = 300 \]
Thus, \( 6 \cdot 10^8 \) is \( 300 \) times larger than \( 2 \cdot 10^6 \).
So, the final answer is:
\[ \boxed{300} \]
