Solution

The number 48,978 can be written in scientific notation by moving the decimal point to the left until only one non-zero digit remains on the left. In this case, we move the decimal point 4 places to the left, which gives us 4.8978.

Since we moved the decimal 4 places, we multiply by 10 to the power of 4 to get the original number back.

So, 48,978 in scientific notation is 4.8978 x 10^4.

Therefore, the correct answer is not given in the options A, B, C, or D. The correct answer should be 4.8978 x 10^4.
