Follow these steps to solve the given equation:
Multiply the two decimal figures together and find the sum of the exponents, that is,
(1.5 * 1.89) * 10 ^4+3
(2.835) * 10^7
10^7 can also be written as e.70
'e' stands for exponential.
Therefore, we have 2. 835 e 7.0 = 2.8 e 7.0.
Based on the calculations above, the correct option is A.
