Solve 117-007a+(3.92a)

$$117 - 007 a + ( 3.92 a )$$

Evaluate

$$\frac{98a}{25}+117$$

Solution Steps

Multiply 0 and 0 to get 0.

$$117-0\times 7a+3.92a$$

Multiply 0 and 7 to get 0.

$$117-0a+3.92a$$

Anything times zero gives zero.

$$117-0+3.92a$$

Subtract 0 from 117 to get 117.

$$117+3.92a$$

Differentiate w.r.t. a

$$3.92$$

Steps Using Derivative Rule for Sum

Multiply 0 and 0 to get 0.

$$\frac{\mathrm{d}}{\mathrm{d}a}(117-0\times 7a+3.92a)$$

Multiply 0 and 7 to get 0.

$$\frac{\mathrm{d}}{\mathrm{d}a}(117-0a+3.92a)$$

Anything times zero gives zero.

$$\frac{\mathrm{d}}{\mathrm{d}a}(117-0+3.92a)$$

Subtract 0 from 117 to get 117.

$$\frac{\mathrm{d}}{\mathrm{d}a}(117+3.92a)$$

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}.

$$3.92a^{1-1}$$

Subtract 1 from 1.

$$3.92a^{0}$$

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

$$3.92\times 1$$

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

$$3.92$$
