Answer 2

Multiply 6 * 3 = 18

When your doing scientific notation you need to have at least one number before the decimal, like 2.####

Now retricethe exponents, -6 + (-8) = -14

18 x 10^-14

1.8 x 10^-13

Answer 3

The quick answer is A, but these aren't so bad. Multiply the two numbers (before the x 10...). The answer is that x 10 to (sum of powers). So in this case, 18 x 10 to the power of (-6 + -8) or -14, which is the same as 1.8 x 10^-13.
