Question

$$2a+30\div3\times4-5$$

Evaluate

$2a+35$

Solution Steps

Divide $30$ by $3$ to get $10$.

$$2a+10\times 4-5$$

Multiply $10$ and $4$ to get $40$.

$$2a+40-5$$

Subtract $5$ from $40$ to get $35$.

$$2a+35$$

Differentiate w.r.t. a

$2$

Steps Using Derivative Rule for Sum

Divide $30$ by $3$ to get $10$.

$$\frac{\mathrm{d}}{\mathrm{d}a}(2a+10\times 4-5)$$

Multiply $10$ and $4$ to get $40$.

$$\frac{\mathrm{d}}{\mathrm{d}a}(2a+40-5)$$

Subtract $5$ from $40$ to get $35$.

$$\frac{\mathrm{d}}{\mathrm{d}a}(2a+35)$$

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 $ax^{n}$ is $nax^{n-1}$.

$$2a^{1-1}$$

Subtract $1$ from $1$.

$$2a^{0}$$

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

$$2\times 1$$

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

$$2$$
