(3 x 10^5) / (12x10^8)

1 answer

To divide these two numbers, we can simply divide their coefficients (3 ÷ 12) and subtract their exponents (5 - 8).

The coefficient is 3 ÷ 12 = 1/4 (or 0.25).

The exponent is 5 - 8 = -3.

Thus, the result is (1/4) x 10^-3 or 0.25 x 10^-3.

We can simplify this by moving the decimal point 3 places to the left:

0.25 x 10^-3 = 0.00025.

Therefore, (3 x 10^5) / (12x10^8) is approximately 0.00025.
