Final answer:
1 x 10^6 is 2 x 10^11 times larger than 5 x 10^-5.
Step-by-step explanation:
To determine how many times larger 1 x 10^6 is than 5 x 10^-5, we need to divide 1 x 10^6 by 5 x 10^-5.
1 x 10^6 ÷ 5 x 10^-5 = (1 ÷ 5) x (10^6 ÷ 10^-5) = 0.2 x 10^11 = 2 x 10^11.
Therefore, 1 x 10^6 is 2 x 10^11 times larger than 5 x 10^-5.
