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.
