A: 9.407x10^-11
b: 94.07x10^-11
c: 9.407x10^-6
d: 9.407x10^-5

Multiply the decimal numbers:

8.18 x 1.15 = 9.407

Now multiply the exponents. When you multiply exponents, with the same whole number, add the exponents together:

10^-6 x 10^-1 becomes 10^(-6 + -5) which equals 10^-11

The final answer is B) 9.407 x 10^-11
