To determine how many times larger 3 x 10^-5 is than 6 x 10^-12, we can divide the two numbers:

(3 x 10^-5) / (6 x 10^-12)

When dividing numbers in scientific notation, we subtract the exponents:

(3 / 6) x 10^(-5 - (-12))

(1/2) x 10^7

Simplifying the fraction and combining the exponents, we get:

0.5 x 10^7

Since 10^7 represents "10 raised to the power of 7," we can express this as:

0.5 x 10,000,000

This can be further simplified to:

5,000,000

Therefore, 3 x 10^-5 is 5,000,000 times larger than 6 x 10^-12.

The correct answer is D) 5 x 10^6.
