We are doing scientific notation and this is the question: (4 x 10^4) (2 x 10^3) it has blank spots for the answer, I don't think they're looking for the answer but how to simplify the question to make it easier to solve. ill take a screenshot cuz I might sound a little confusing

I put a screenshot of the question below

the answer for this question is 38

step-by-step explanation:

if you want to solve percent error follow these steps.

1. subtract the accepted value from the experimental value.

2. take the absolute value of step 1.

3. divide that answer by the accepted value.

4. multiply that answer by 100 and add the % symbol to express the answer as a percentage.

if you want to solve percent of change just do this.

1. work out the difference (increase) between the two numbers you are comparing.

2. divide the increase by the original number and multiply the answer by 100. if your answer is a negative number then this is a percentage decrease.

hope this : )
