Solve 2a^2/4a

$$\frac { 2 a ^ { 2 } } { 4 a }$$

Evaluate

$$\frac{a}{2}$$

Steps for Quotient of Exponentials

Use the rules of exponents to simplify the expression.

$$\frac{2^{1}a^{2}}{4^{1}a^{1}}$$

To divide powers of the same base, subtract the denominator's exponent from the numerator's exponent.

$$\frac{2^{1}a^{2-1}}{4^{1}}$$

Subtract 1 from 2.

$$\frac{2^{1}a^{1}}{4^{1}}$$

Reduce the fraction \frac{2}{4} to lowest terms by extracting and canceling out 2.

$$\frac{1}{2}a^{1}$$

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

$$\frac{1}{2}a$$

Differentiate w.r.t. a

$$\frac{1}{2} = 0.5$$

Solution Steps

To divide powers of the same base, subtract the denominator's exponent from the numerator's exponent.

$$\frac{\mathrm{d}}{\mathrm{d}a}(\frac{2}{4}a^{2-1})$$

Do the arithmetic.

$$\frac{\mathrm{d}}{\mathrm{d}a}(\frac{1}{2}a^{1})$$

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}.

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

Do the arithmetic.

$$\frac{1}{2}a^{0}$$

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

$$\frac{1}{2}\times 1$$

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

$$\frac{1}{2}$$
