Answer 1

To determine how many times larger \( 9 \times 10^{-8} \) is than \( 3 \times 10^{-12} \), you can divide the two numbers:

\[
\frac{9 \times 10^{-8}}{3 \times 10^{-12}}
\]

First, divide the coefficients (9 and 3):

\[
\frac{9}{3} = 3
\]

Next, divide the powers of ten. When dividing, you subtract the exponents:

\[
10^{-8} \div 10^{-12} = 10^{-8 - (-12)} = 10^{-8 + 12} = 10^{4}
\]

Now, combine the results:

\[
3 \times 10^{4}
\]

Thus, \( 9 \times 10^{-8} \) is \( 3 \times 10^4 \) times larger than \( 3 \times 10^{-12} \).

The correct answer is:

**3×10⁴**
