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 treatas, since anything to the zero power is one.

This means thatis the same as.

Now use the power rule:

Anything times zero is zero.

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 treatas.

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.

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,.

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.

To take the second derivative, we need to start with the first derivative.

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.

Now we repeat the process, but usingas our expression.

We're going to treatas beingsince anything to the zero power is equal to one.

请注意,since anything times zero is zero.

To take the second derivative, we need to start with the first derivative.

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 treatassince anything to the zero power is one.

请注意,since anything times zero is zero.

Simplify.

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

Now we repeat the process but use, or, as our expression.

As stated before, anything times zero is zero.

Therefore,.

To find the second derivative, first we need to start with the first derivative.

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.

Now we repeat the process usingas our expression.

We're going to treatas.

请注意,since anything times zero is zero.

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

To find the second derivative, we start by taking the first derivative.

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.

Now we repeat the process but usingas our expression.

Remember, anything to the zero power is one.

To find the second derivative, we need to start by finding the first derivative.

To find the first derivative for this problem, we can use the power rule. The power rule states that we lower the exponent of each of the variables by one and multiply by that original exponent.

Remember that anything to the zero power is one.

Now we repeat the process, but we useas our expression.

For this problem, we're going to say thatsince, as stated before, anything to the zero power is one.

请注意,as anything times zero is zero.
