Answer:
The answer is B.
Step-by-step explanation:
To express a number in scientific notation it has to be expressed in the form a x 10^n
Where 1 < a < 10 and n is an integer
rewrite 1236 as a number between 1 and 10 ie. 1.236 and to get it equal to it's original value we have to multiply by 1000.
So 1236 = 1,236 * 10^3
