Solve =(2(-1)-5(1)^2)/(4-(1)^4)

$$= \frac { ( 2 ( - 1 ) - 5 ( 1 ) ^ { 2 } ) } { ( 4 - ( 1 ) ^ { 4 } ) }$$

Evaluate

$$-\frac{7}{3}\approx -2.333333333$$

Solution Steps

Multiply 2 and -1 to get -2.

$$\frac{-2-5\times 1^{2}}{4-1^{4}}$$

Calculate 1 to the power of 2 and get 1.

$$\frac{-2-5\times 1}{4-1^{4}}$$

Multiply 5 and 1 to get 5.

$$\frac{-2-5}{4-1^{4}}$$

Subtract 5 from -2 to get -7.

$$\frac{-7}{4-1^{4}}$$

Calculate 1 to the power of 4 and get 1.

$$\frac{-7}{4-1}$$

Subtract 1 from 4 to get 3.

$$\frac{-7}{3}$$

Fraction \frac{-7}{3} can be rewritten as -\frac{7}{3} by extracting the negative sign.

$$-\frac{7}{3}$$

Factor

$$-\frac{7}{3} = -2\frac{1}{3} = -2.3333333333333335$$
