Question

$4x {4} + 81$
​

Answer 1

A n s w e r :

• The answer of the given question is 4 by using Derivative Rule for Sum.

G i v e nㅤT h a t :

• $\bf 4x4 + 81.$

T oㅤF i n d :

• The answer of the given question by using Derivative Rule for Sum.

S t e p - b y - s t e pㅤE x p l a n a t i o n :

ㅤㅤ:→ $\bf 4x4 + 81.$

[The derivative of a polynomial is the sum of the derivatives of its terms. The derivative of a constant term is 0. The derivative of $\rm ax^{n}$ is $\rm nax^{n-1}$.]

ㅤㅤ:→ $\sf 4x_{4}^{1-1}$.

Subtract 1 from 1.

ㅤㅤ:→ $\sf 4x_{4}^{0}$.

For any term$\rm{\;}_t$ except 0, $\rm t^{0}=1$.

ㅤㅤ:→ $\sf 4\times 1$.

For any term$\rm{\;}_t$, $\rm t\times 1$ → t and 1t → t.

ㅤㅤ:→ $\underline{\boxed{\bf {4}}}\;\:\bigstar$.
