Question

$$253x795$$

Evaluate

$253x_{795}$

Steps For Long Multiplication

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

$$\begin{array}{c}\phantom{\times999}253\\\underline{\times\phantom{999}795}\\\end{array}$$

Now multiply the first number with the $1^{st}$ digit in $2^{nd}$ number to get intermediate results. That is Multiply 253 with 5. Write the result 1265 at the end leaving 0 spaces to the right like this.

$$\begin{array}{c}\phantom{\times999}253\\\underline{\times\phantom{999}795}\\\phantom{\times99}1265\\\end{array}$$

Now multiply the first number with the $2^{nd}$ digit in $2^{nd}$ number to get intermediate results. That is Multiply 253 with 9. Write the result 2277 at the end leaving 1 spaces to the right like this.

$$\begin{array}{c}\phantom{\times999}253\\\underline{\times\phantom{999}795}\\\phantom{\times99}1265\\\phantom{\times9}2277\phantom{9}\\\end{array}$$

Now multiply the first number with the $3^{rd}$ digit in $2^{nd}$ number to get intermediate results. That is Multiply 253 with 7. Write the result 1771 at the end leaving 2 spaces to the right like this.

$$\begin{array}{c}\phantom{\times999}253\\\underline{\times\phantom{999}795}\\\phantom{\times99}1265\\\phantom{\times9}2277\phantom{9}\\\underline{\phantom{\times}1771\phantom{99}}\\\end{array}$$

Now add the intermediate results to get final answer.

$$\begin{array}{c}\phantom{\times999}253\\\underline{\times\phantom{999}795}\\\phantom{\times99}1265\\\phantom{\times9}2277\phantom{9}\\\underline{\phantom{\times}1771\phantom{99}}\\\phantom{\times}201135\end{array}$$

Steps Using Definition of a Derivative

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

$$253x_{795}^{1-1}$$

Subtract $1$ from $1$.

$$253x_{795}^{0}$$

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

$$253\times 1$$

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

$$253$$
