Example Question #1 : Derivative Defined As The Limit Of The Difference Quotient

What is the derivative of ?

Possible Answers:

Correct answer:

Explanation:

To take the derivative of this equation, we can use the power rule. The power rule says that we lower the exponent of each variable by one and multiply that number by the original exponent.

Simplify.

Remember that anything to the zero power is equal to one.

Example Question #2 : Derivative Defined As The Limit Of The Difference Quotient

What is the derivative of ?

Possible Answers:

Correct answer:

Explanation:

To take the derivative of this equation, we can use the power rule. The power rule says that we lower the exponent of each variable by one and multiply that number by the original exponent.

We are going to treat  as  since anything to the zero power is one.

Notice that  since anything times zero is zero.

Simplify.

As stated before, anything to the zero power is one.

Example Question #3 : Derivative Defined As The Limit Of The Difference Quotient

What is the derivative of ?

Possible Answers:

Correct answer:

Explanation:

To find the first derivative, we can use the power rule. We lower the exponent on all the variables by one and multiply by the original variable.

Anything to the zero power is one.

Example Question #621 : Derivatives

What is the derivative of ?

Possible Answers:

Correct answer:

Explanation:

To find the first derivative, we can use the power rule. We lower the exponent on all the variables by one and multiply by the original variable.

We're going to treat  as  since anything to the zero power is one.

For this problem that would look like this:

Notice that  since anything times zero is zero.

Example Question #31 : Calculus I — Derivatives

What is the derivative of ?

Possible Answers:

Correct answer:

Explanation:

To find the first derivative, we can use the power rule. To do that, we lower the exponent on the variables by one and multiply by the original exponent.

We're going to treat  as  since anything to the zero power is one.

Notice that  since anything times zero is zero.

 

Example Question #41 : Calculus I — Derivatives

Possible Answers:

Correct answer:

Explanation:

To find the derivative of the problem, we can use the power rule. The power rule says to multiply the coefficient of the variable by the exponent of the variable and then lower the exponent value by one.

To make that work, we're going to treat  as , since anything to the zero power is one.

This means that  is the same as .

Now use the power rule:

Anything times zero is zero.

Example Question #42 : Calculus I — Derivatives

What is the first derivative of ?

Possible Answers:

Correct answer:

Explanation:

To find the derivative of , we can use the power rule.

The power rule states that we multiply each variable by its current exponent and then lower the exponent of each variable by one.

Since , we're going to treat  as .

Anything times zero is zero, so our final term , regardless of the power of the exponent.

Simplify what we have.

Our final solution, then, is .

Example Question #2111 : High School Math

If , what is ?

Possible Answers:

There is no  for this equation.

Correct answer:

Explanation:

For this problem, we can use the power rule. The power rule states that we multiply each variable by its current exponent and then lower that exponent by one. 

Simplify.

Anything to the zero power is one, so .

Therefore, .

Example Question #44 : Calculus I — Derivatives

Find the derivative of the following function:

Possible Answers:

Correct answer:

Explanation:

We use the power rule on each term of the function.

The first term

becomes

.

The second term

becomes

.

The final term, 7, is a constant, so its derivative is simply zero.
