Find (23.9 x 108) - (21.4 x 108). Express your answer in scientific notation.

The answer is 2.7×10^2

Step-by-step explanation:

Move the decimal so there is one non-zero digit to the left of the decimal point. The number of decimal places you move will be the exponent on the 1010. If the decimal is being moved to the right, the exponent will be negative. If the decimal is being moved to the left, the exponent will be positive. hope this helps you :)
