Solve 3a-b/4)^4

$$3 a - \frac { b } { 4 } ) ^ { 4 }$$

Evaluate

$$-\frac{b}{4}+3a$$

Short Solution Steps

To add or subtract expressions, expand them to make their denominators the same. Multiply 3a times \frac{4}{4}.

$$\frac{4\times 3a}{4}-\frac{b}{4}$$

Since \frac{4\times 3a}{4} and \frac{b}{4} have the same denominator, subtract them by subtracting their numerators.

$$\frac{4\times 3a-b}{4}$$

Do the multiplications in 4\times 3a-b.

$$\frac{12a-b}{4}$$

Factor

$$\frac{12a-b}{4}$$

Solution Steps

Factor out \frac{1}{4}.

$$\frac{12a-b}{4}$$
