eval rand(2,3);
eval rand(12,19);
eval rand(1,3)
eval (2*1)+1;
eval (-1*3);
eval pow((15-3*pow(3,2)),4);
eval pow(3,8);

Evaluate the limit using the Basic Limit Laws and limits and

 
Step 1

Recall that the Power Law states that for any positive integer n,

Question Sequence

Question 1

Apply the Power Law to the given problem.

z =

2
Correct.
Try again.
Incorrect.

 
Step 2

Recall that the sum law states that if and exist, then exists and

Question Sequence

Question 2

Apply the sum law to

z =

2
Correct.
That's not right. Check your work.
Incorrect.

 
Step 3

Recall that the Product Law states that if and exist, then

.

We can apply the Product Law to since it can be expressed as .

Question 4

Apply the Product Law to

z =

2
Correct.
That's not right. Check your work.
Incorrect.

Note: we could have also used the Power Rule to find this limit.

 
Step 4

Evaluate the limit using the Basic Laws and the limits and .

Question 5

where w= and z=.

Thus the value of the limit (rounded to two decimal places) is .

2
Correct.
When applying the Limit Laws, in the last step, make the appropriate substitutions and evaluate.
Incorrect.
