Solve 52x98

$$52x98$$

Evaluate

$$52x_{98}$$

Steps For Long Multiplication

First line up the numbers vertically and match the places from the right like this.

$$\begin{array}{c}\phantom{\times99}52\\\underline{\times\phantom{99}98}\\\end{array}$$

Now multiply the first number with the 1^{st} digit in 2^{nd} number to get intermediate results. That is Multiply 52 with 8. Write the result 416 at the end leaving 0 spaces to the right like this.

$$\begin{array}{c}\phantom{\times99}52\\\underline{\times\phantom{99}98}\\\phantom{\times9}416\\\end{array}$$

Now multiply the first number with the 2^{nd} digit in 2^{nd} number to get intermediate results. That is Multiply 52 with 9. Write the result 468 at the end leaving 1 spaces to the right like this.

$$\begin{array}{c}\phantom{\times99}52\\\underline{\times\phantom{99}98}\\\phantom{\times9}416\\\underline{\phantom{\times}468\phantom{9}}\\\end{array}$$

Now add the intermediate results to get final answer.

$$\begin{array}{c}\phantom{\times99}52\\\underline{\times\phantom{99}98}\\\phantom{\times9}416\\\underline{\phantom{\times}468\phantom{9}}\\\phantom{\times}5096\end{array}$$

Differentiate w.r.t. x_98

$$52$$

Steps Using Definition of a Derivative

The derivative of ax^{n} is nax^{n-1}.

$$52x_{98}^{1-1}$$

Subtract 1 from 1.

$$52x_{98}^{0}$$

For any term t except 0, t^{0}=1.

$$52\times 1$$

For any term t, t\times 1=t and 1t=t.

$$52$$
