Explanation

To simplify $1.2 times 10^{48} + 1.2 times 10^{41}$ factor out the common coefficient:

$$1.2 times (10^{48} + 10^{41})$$

Since $10^{48}$ is much larger than $10^{41}$, $10^{48} + 10^{41} approx 10^{48}$

$$
Thus, the expression simplifies to:

$$1.2 times 10^{48}$$

The sum remains close to $1.2 times 10^{48}$not multiplied significantly.

Hence, the correct answer is "None."
