B(3X10 by the power of 8

Explanation:

Answer 2

`\large \boxed{\text{(B) } 3* 10^(8)}`

Explanation:

To figure out how many times a number is than another, you divide the larger number by the smaller.

Here, your numbers are expressed in scientific notation, so you

1. Divide the coefficients and the exponentials separately

`(12 * 10^(12))/(4 * 10^(4)) = (12)/(4) * (10^(12))/(10^(4))`

2. Divide the coefficients

`(12)/(4) = 3`

3. Divide the exponentials

Subtract the exponent in the denominator from the exponent in the numerator.

`(10^(12))/(10^(4)) = 10^((12 - 4)) = 10 ^(8)`

4. Re-join the new coefficient and the new exponential

`(12 * 10^(12))/(4 * 10^(4)) = \large \boxed{\mathbf{3* 10^(8)}}`
