Can someone explain this for me i’m
not sure of the steps. see photo above

Question 1:

We have the following expression:

By definition of power properties we have to:

Then, rewriting the expression:

Question 2:

For this case we have the following expression:

By definition of power properties of the same base we have:

Then, we can rewrite the denominator of the expression as:

Simplifying terms of the numerator and denominator:

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 : )
