Question

Calculate the following:

1.5x104 x 1.89x103 = ??

Select one:
a. 2.8 e7.0
b. 2.8 e1.0
c. 0.79 e7.0
d. 0.79 e1.0

Answer 1

The equation can be solved by following these steps:
(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.
Thus, the correct option is A.
