Solve (-1)^7(7^2+1)/4(7)

$$\frac { ( - 1 ) ^ { 7 } ( 7 ^ { 2 } + 1 ) } { 4 ( 7 ) }$$

Evaluate

$$-\frac{25}{14}\approx -1.785714286$$

Solution Steps

Calculate -1 to the power of 7 and get -1.

$$\frac{-\left(7^{2}+1\right)}{4\times 7}$$

Calculate 7 to the power of 2 and get 49.

$$\frac{-\left(49+1\right)}{4\times 7}$$

Add 49 and 1 to get 50.

$$\frac{-50}{4\times 7}$$

Multiply 4 and 7 to get 28.

$$\frac{-50}{28}$$

Reduce the fraction \frac{-50}{28} to lowest terms by extracting and canceling out 2.

$$-\frac{25}{14}$$

Factor

$$-\frac{25}{14} = -1\frac{11}{14} = -1.7857142857142858$$
